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

Main constituents (%)

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: If I were to use it for a ton of paper and chipboard like material - would it bind paper well and stick? Or is there another glue that's stronger?: Rubber cement is good in some cases for paper because it doesn't cause water damage to the paper (curling, wrinkling, shriveling, etc.) However, it really doesn't create a strong bond with paper, and can peel off with little trouble. It is not archival approved, and will cause damage to paper over time. I wouldn't use it for anything I wanted to keep.

Q: I used bleach to whiten the netting a while back but I forgot to completely wash it out so now they're mad yellow and it's killing me cuz they were my favorite pair. I've heard of Retrobrite and was thinking of using that but I wanted to see if there are other ways to whiten them, like a cleaning gel from Foot Locker, Finish Line or Champs. Thanks I appreciate any ideas.: You need to use some sort of sauce that is made to whiten sneaker soles. Most of those products will work just as well on any type of rubber, including netting, midsoles, or any other rubber areas on the sneaker. I've heard Air Legends makes good sauce, so I bought a bottle, to use on the netting on my Air Jordan 4 White Cements. I just haven't had a chance to use it yet, but I plan on it this weekend. You can even use it on the heel tabs of the Jordan 4s (the part with the Jumpman logo, or Nike Air for the older releases). PS: For any of you kids out there, do NOT use bleach! It would seem like that would work, but like the OP, it made the netting on my Jordan 4s more yellow than they were when I applied the bleach!

Q: I have built a dry stacked concrete block wall as a fence around our home. I am wondering if I should use premixed cement or mix it myself. What is the best mix recipe for a Surface Bonding Cement mix?: Your location will influence the decision to buy premix or use a DIY mix. If you can easily buy the premix locally, that will probably be your best choice. The premix will usually have a better feel and probably performance because the manufactures have the ability to engineer the product on a much larger scale than can be done onsite. Since the original guide was published there have been many improvements to the available additives. The Calcium Chloride and Calcium Stearate may no longer be the best choice for surface bonding mix.

Q: Does rubber cement float?: depends if it has a higher or lower density than water

Q: I am studying for an exam and I desperately need information on placement issues and pumpability in oil and gas cementing. Thanks in advance: You okorder ). Most of the published information has to be purchased through the Society of Petroleum engineers. Off the top of my head, some of the issues are being able to pump a heavy viscous fluid like cement across under pressured formations. You have to apply enough pressure to move the cement, but you have to stay below the fracture pressure of the rock formations. If you don't, the formation will break down and the cement will flow in to that zone, called a thief zone, and cement will not make it all the way up the casing. The other issue is keeping casing centralized in the wellbore so that cement will be placed evenly around the casing. If the casing is not centered, then the cement may not might not completely encase the casing, leaving void spaces where channels can form, where oil and gas could flow.

Q: As in many modern houses, our en-suite shower is made up of tiles fixed onto plaster board. Over the years this has started to leak as the grouting failed, and the plaster board has become soggy and needs replacing. We have had two suggestions from different builders. One suggests ripping out the old plaster board and replacing it with quot;cement boardquot; onto which tiles would be stuck. The other suggestion involves cutting out the old plaster board, replacing it with new plaster board which would then be quot;sealedquot; before tiles are stuck onto it. Does anyone know which of these would be the better option please? Costs of both proposals appear to be similar so we really want the better engineering solution.: I am no expert other than the re-muddling I have done around my own home, but I would say that the cement board route would be the better way to go. No matter how well sealed the plaster board is, it will eventually draw moisture due to the constant exposure over the years. Before the plaster board is installed, the shower pan should be installed. The plaster board is then installed to sit just off the lip on the inside of the shower pan but not above the edge of the pan. When they install the cement board (which, by the way, is used as exterior siding on homes in the south) make sure they tape and seal all the joints, a process similiar to installing wallboard, but done with a mesh tape and mortar, instead. A reputable drywaller or tiler should know to do this, but I would make sure ... this is no time for misunderstandings. Water damage inside a house can cause a multitude of problems, not the least of which is the shower coming through the downstairs ceiling one night when the boss is over for dinner.

Q: When preparing mortar, why in addition to cement, but also often add a certain amount of other cementitious materials: Then there are cement and other building materials and cementitious materials have a great relationship And the gelling material has some excellent performance, in the daily life of the more widely used With the scientific development of cementitious materials, cementing materials and their products industry will produce a new leap

Q: my son got some new posters and wants to hang them up. he has a very light blue (almost white) color painted on his walls (with panelling behind it) and i wanted to know if i could use rubber cement to hang them, or if it would damage the paint color after removal?: There are actually packages of little sticky balls (grey, consistency of gum) that you can use. The schools all use it to put posters up on their walls. It's the same stuff that comes with the glow-in-the-dark stars and planets that some kids put on their ceilings...

Q: its for my physics assignment..thanks!: it absorb energy... such as heat..force or pressure ..

Q: How to start a cement factory?: Are you talking about a plant that supplies bags of cement mix like you'd buy at Home Depot, or a plant where you fill the cement mixer trucks and they go out and pour the stuff into whatever? Either way, the easiest way might be to find a defunct one and reopen it.
