HCSA BINDER is manufactured under a strict quality assurance systems GB/T 19001-2000 and GB/T 24001-1996 which accommodates the

Chemical Analysis

The chemical analysis of HCSA BINDER has been determined according to the following:

GB/T 176-1996 Methods of chemical analysis for cement

Main constituents (%)

HCSA Cement

Fineness

Specific Surface Area: according to standard GB/T 8074-1987

Usual range: 360~430 m2/kg

Specification limit: >360 m2/kg

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:please help...: IT IS VERY HARM FULL

Q:l need to know- thankyou,xx jo: i think cement

Q:We have an odd shaped living room and the way we have it arranged our couch is sitting in front of the woodstove. It has not been a problem since it has been warm out and we have not been using the stove, but now that fall weather is here we are getting to the point that we are going to have to use it. Our couch sits about 2 feet in front of the stove with the back of the couch facing the stove, its enough room for a person to walk between the couch and stove without touching the stove. I need to know if we can attach a piece of cement board that has ceramic tile on it to the back of our couch to make it safe from getting too hot and causing a fire. Thanks.: To answer your question, yes, it would be okay to install a cement particle board to the back of your sofa, to provide a barrier between the stove and the sofa. If you choose to go with this option, purchase the ones with higher fire resistance and install the wall backing from the bottom of the couch, to a height high enough to protect people's heads. But. if there is enough space, it would be better to move the couch further from the stove instead. In fact, if you can move some stuff around, it would be much better to shape your furniture like a U, with the open end facing the stove. Just as you would fix it around a fireplace. Because it isn't just the couch you need to protect, it is also the people sitting on it. Flying embers could scorch hair and clothing as well. And if you have small kids, regardless of what you tell them, they will once in a while forget and will pass through the space between the stove and the couch. With a U-shape, there is a better chance that they will pass between furniture, as opposed to between furniture and stove.

Q:13 inch diameter solid concrete stone - yes it will be heavy = approximately 90-95lbs.: hoe high is the stone

Q:For a science projekt i need to use a material that is stronger than plaster but not to heavy like cement or if u know a brand of plaster that is really strong or vice versa with cement please tell me. it would be great If the cost is less than 50 dollars for 10kg than: you can put in the web cement plaster...yoy will get lots of information cement adhesive and cost plaster of paris araldite some people mix gum with cement u can ask in web ligher adhesive used with cement then ask for the price

Q:i am having a fence installed, i have quotes from 2 different contractors... one pounds the posts into the ground, the other cements each post into the ground, how deep either go i am not sure... but which way would be more secure long term? the posts are the same as used for a chain link fence (steel posts)... thanks: Cement 4 sure..pounding them in is weak...not to even mention the added risk of breaking a gas line due to not being able to see what you are doing. Think about it ...with cement you have the added weight for strength...pounding them alone is weak.

Q:hey guys i know what the blue cement does for my teeth it helps me not to touch my bottom teeth giving it space but was wondering does it get better in a week or two? i have the blue cement on both of my molars and i have braces on both upper and bottom teeths. Does chewing get any better? i cannot chew properly and it hurts a bit. also when do the orthondontist take the blue cement off?: Uuuggggghh the blue cement. I hated that stuff. The texture was so weird and... bleh. Anyway, it took me about a month, maybe 3 weeks, before chewing got to be more normal, once the cement started wearing down. Don't worry, eventually it does wear down and you'll be able to eat like normal. The orthodontist will take the cement off when your overbite is improved enough. For me, it took about... 10 months, I think. But it all depends on your individual case, and your orthodontist. I know one girl whose ortho never actually removed the cement. She doesn't care, because the blobs are so tiny by now, but it happens.

Q:I live in a bright purple cement rendered home and want to paint it dark grey, but am unsure what paint to use or if I have to do any preparation to it before painting itPlease helpBrands available in Australia will helpThanks: First, try using a power washer in the 2000 PSI range to take off the old paint. If it comes off (or most of it, anyway), let the cement dry for a couple days and then use a concrete primer before applying a color coat specifically made for concrete. The primer is especially acidic, so it really soaks into the cement (and it doesn't go very far, because so much soaks into the concrete). The concrete color coat is then designed to hold onto the primer and provide a solid moisture barrier. If the old color won't come off, don't worry. Just clean it up as best you can before applying the primer and paint. And, use top name brand paints (like Dunn-Edwards or Sherman Williams). The more expensive products will cover better and may actually be cheaper in the long run (less coats and time to paint).

Q:I need to semi-permanently hang items on a cement wall. What is the best way to go about doing so?: Hook and loop (velcro) tape. Glue one side to your item, and one side to the cement....larger pictures will need tape around all four edges to be secure, but it does work - I've done it before. Hope this helps. Good luck!

Q:What is Oilfield cement, is it the same as the cement that cars drive on?: I have never worked in the Oil Patch, but I believe oilfield cement is a mixture of sand, aggregate and a barium compound (barium carbonate, maybe). If you look at the Periodic Table, you will see that barium lies under calcium, and has the same properties (more or less). Since barium is denser, when an over-pressured oil reservoir is breached, this mixture plugs up the drill hole until the well can be capped. This is a major use of the element barium.
