Reactivity with Portland cement

HCSA BINDER may be used in combination with other mineral products, for example PORTLAND cement, calcium sulphates and fillers, or with organics such as polymers in latex form or in redispersible form.

Depending on the type of mixes and technology employed, HCSA BINDER can be used to obtain and control various properties.

The behaviour of PORTLAND cement is vary variable. In general, acceleration of set increases progressly with the addition of HCSA BINDER. The amount of HCSA BINDER needed to obtain a specific setting time varies considerably depending on the origin of the PORTLAND cement and performance can be modified with the use of additives.

The strength development of HCSA BINDER/PORTLAND cement and/or Calcium Sulphates depend on the nature of the PORTLAND cement and/or Calcium Sulphates used. In general these mixes will develop mechanical strength at a very early stage (several hours). With some type of PORTLAND cements and in formulated products containing additives which control the setting and hydration, the long term properties is similar to those of the original PORTLAND cement, however it is necessary to check the behaviour of each PORTLAND cement used.

The characteristics of PORTLAND cement to be considered are:

1. C3A content

2. Mineral admixture type and content

3. Type of Calcium Sulphate used

Additives will also influence the properties of these mixes:

1. Setting time

2. Rheology

3. Mechanical performance

These properties are applied to obtain a wide range of products:

1. Fast setting cements

2. Rapid hardening mortars

3. Tile adhesives

4. Self-leveling compounds

5. Non-shrink grouts

6. Water stopping mortars

7. etc.

With a careful selection of the constituents (OPC, calcium sulphates, additives), it is possible to create mixes with a range of different hydraulic properties:

1. Adjustable setting time

2. Rheology adapted to the application

3. High early strength

4. High long term strength

5. Shrinkage compensation

Use of Additives

HCSA BINDER may be used in combination with chemical additives such as:

1. polymers, either in latex form or redispersible powder form

2. defoamers

3. retarders

4. accelerators

5. plasticizers/superplasticizers

6. rheology modifiers

7. fibers

Q:given only the volume of the project...: Too long for simple answer, see websites below:

Q:I want to determine the percentage of Chloride present in any cement. Then can any one tell mePl., the standard method of determination of percentage of chloride in any type of cement.: figure out what the cement is made of in terms of chemical formula. use Cl5S2 as a rhetorical example *by the way, thats way off, divide the number of chlorine by the the total number of atoms in the formula. so in the example, its 5/ (5+2), which is about 0.714, so in the example there is 71.4% chlorine/ chloride

Q:We are in the middle of a kitchen remodel. We removed the old linoleum floors and there are wood planks that run north to south. Currently, this layer is flush with our living room wood floors. From the basement, you can see that there are boards that run west to east where the kitchen is.My question is, if I remove the wood planks that run north to south, can I put down a layer of cement board and just start tiling over the west to east boards? Will the weight be a structural issue? I would leave the north to south boards, but I'm worried about a tripping hazard being presented when I put down cement board, grout, and 1/2quot; tile (would probably be 1quot; all together). Trying to stay away from ramps, also. Thanks.: Are you saying there's 2 layers of boards on top of the floor joists? If yes then removing the top layer would be the way to go if the bottom sub-floor layer is strong enough to not be springy under concentrated loads or if you can beef it up by installing bridging underneath between the joists. If the sub-floor is the only layer then you'd not want to remove that since the structural integrity of the house would be affected and the cement board wouldn't be properly supported.

Q:how do we calculate how much we need and how is it done: I do not know how you will keep it from settling but as to the volume 2 = .166 ft average height is 10' = 5/6 = .833 ft I assume a steady slope so I use average thickness 22.166 x 360.166 x .833 = 6,650.2 cu ft = 246.3 cu yds

Q:I remember our new middle school (back when I was in middle school) was brand new. And most kids have a (non-serious) fantasy about their school burning down, but it almost entirely made of painted cement blocks.Cement, I think can be burned/charred if say you hold a blowtorch/flamethrower to it, or douse it with gasoline and ignite it, but I don't think it can catch fire and have it spread like wood can. I know the twin towers collapsed but that was because an plane flew into them. It was the engine fuel that burned it. For a fire to catch and spread and become really strong, it needs some decent food/combustible fuel like wood to get a strong fire going.: Many concrete or steel structures use wooden supports in various ways, most importantly as roof or floor trusses. These can fail within minutes of a serious fire breaking out, which is why many jurisdictions require they be clearly marked for firefighter safety. Also, as mentioned, the contents of most schools are ordinary fuels that include combustible wood, cloth, paper of various kinds, not to mention synthetic plastics (carpets, wiring, furniture stuffing) and coatings (paints), all of which could make a fuel load sufficient to burn the place down. Unlike the popular myth, steel structures are very unlikely to melt (at less than 2,500 F), but steel under stress will easily DEFORM when heated, including the temperatures reached by burning jet fuel and routinely found in fully-involved structure fires.

Q:I want to lay cement all along the bottom of the whole fence , keeping the fence from touching the grass and also keeping my dogs from digging out ?? I just dont know how thick the footer should be or how wide .. Anyone ??: since what you are doing is not for structural support, the idea of code doesn't apply. Your choices are completely based on your needs and the building materials chosen. SO, you say cement, I believe you mean concrete (water + cement + gravel = concrete), Concrete needs to be at least 2 thick (check the bag) usually 4 for slabs . Since your depth concern is based on how deep your dogs dig, check out some of their work, it needs to be deep enough to at least dissuade them from digging. so let say....10 deep x 4 wide, and lets say you want to come about two inches above the ground so, as you said, your fence doesn't touch the grass. Next you will be amazed at how much concrete you will need for a fenceline. Say 50 feet of fenceline (not much), 50 feet long x 12 inches (1 foot) deep (10down/2up) x 4 inches wide (1/3 foot), 50 x 1 x .33 = just under 17 cubic feet of concrete @ just under 1/2 cubic foot / 60 lb. bag, means you will need approx 35, 60 lb bags (mixing it is alot of work) BTW, what you want to do (for the above example) is dig down 10 deep x 4 wide, then place a 2 x 3 (or 4) flat on the ground on each side of the ditch, put spikes in so the wood doesn't move, fill to the top of the wood with concrete, smmoth (screed) a board acroos the top to level and remove excess. wait 24 hrs, remove wood. you now have a 1 1/2 inch rise above the ground. my 2 cents

Q:how many bags of cement will i have to buy if i wanted to fill a 5 gallon bucket?i am going to fill it half full, put a friend of mines' Christmas present into it, and then cover the rest.I worked in concrete for two years so i know how to set it all up, but we generally dealt with trucks of concrete, not buckets.so. how many bags? or how many pounds?: If you are going to use straight cement one 80 lb. bag, 2/3 of a cubic foot, will fill your five gallon bucket, with some left over because of the present. Five gallons is 2/3 of a cubic foot. If you are going to use a mix with aggregate and water a gallon of cement will be more than enough.

Q:over the years the cement floor has settled and broken at the opening of the overhead door. can someone tell me the right way to do the repairs, or send me to a site that i could get some directions. one of my main concerns is the side jams of the doorway. can you fill the level of cement above the boards? Thanks for your help.: Is your concern to resurface the whole area. You need a few helping hands to do the repair. First, break up the old cement floor and compact the ground with sand and the broken pieces with a compactor.This is the base for the cement floor.Allow another 3 inches height for the new concrete floor. Water the whole area to fill all gaps ,refill with sand and compact again. Mark out with string for level gradually running outward from the door entrance. Do not adjust the level above the door jamb to prevent water ingress during rain. Lay a layer of wire mesh on it.Mix cement ,sand and stones/pebbles in proportion of 1:3 :6 with water to form a slurry mix and fill up the floor.Trowel the entire areas evenly with a gradient to allow water to flow toward drain or channels. Remember not to make the floor too smooth as it may turn slippery when wet. Cure the concrete by sprinkling water on it for the next few days or just keep in cool. The job is completed. 10 points please.

Q:So not too long ago I got a permanent retainer glued to the top of my teeth. My sister told me that her permanent retainer once fell off and it got me paranoid. I just go it on so the cement is relatively fresh but I rub the glue with my tongue and now I have a question... How strong is the cement? Can I eat and drink whatever or will certain foods and drinks ruin and wear the glue away? Should I brush and floss there gentler as to not wear the glue away? I hear all these stories of where the glue sometimes falls off in little chunks or something and they have to get their retainer re-glued on and so I ask how long will the glue last on my teeth before it starts to fade? Is the cement/glue strong enough to last awhile? Etc.: Whether or not it comes off is dependent on two things, really: 1: you not eating dumb things, like gum or air heads, etc. and 2: your bite. Some just do. The glue will stay as long as the bond took. Some may chip off from your bite, but there's not a lot you can do aside from being careful to stay away from foods that you are not supposed to eat. The glue can last years and years. It's the same stuff we use to cement crowns and it lasts decades. But adults don't do the same dumb stuff with their mouths that kids do.
