Product Description:

 

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

 

 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:Which way is better to install steel posts for a fence, pounding them in or cementing?
Cementing the posts in the ground will hold longer. My Dad put up fencing all his life and this was his preferred method. He was always pointing out fences that he put up 20 or more years before.
Q:need help with cement floor repair.?
I would start with preventing the floor from further settelment. once your base is secure you can work on the crack that is there. Hard to advise on how to prevent without knowing more info. Depending on how large the crack is, you want to fill it and seal it. Larger cracks can be filled with a foam backer rod material (up to half inch depending on the backer rod you buy) and there are many types of crack fillers. before using a crack filler, make sure you get any loose debris out as that will hinder bonding. This type of job is all about prep work and prevention. quick solutions will only result in further cracking in the future.
Q:Can a cement, or a metal building burn down?
Cement/concrete and metal are not combustible. The problem is that things inside the building can burn and make toxic gases that will kill you.
Q:can u explain cement manufacturing?
That could be a very hard question to answer, particularly if you add water.
Q:can ticks be found on cement?
Animals can pick up ticks wherever the ticks are at. A tick commonly will stay on an animal until they have fully gorged, and then fall off. That is why they can be most anywhere, it is a matter of where they fell off at. They really do prefer under pines, but can be found most anywhere since they are able to move on their own. For your rabbit, ask a vet about frontline or advantage treatment to keep him tick free. Good luck.
Q:Wooden or cement walls - which one has better sound insulation?
Any structure of walls and ceilings will only provide minimal soundproofing unless you add a soundproof material to them like, styrofoam, cork, or fabric covered fiberglass. all of these materials are designed to absorb sound. Sound will bounce off a concrete wall more because of its density, but I would definitely use some sort of soundproofing if you need it to conceal noise. In recording studios I have used fabric covered sound insulation.
Q:how much gravel and sand could be mixed for 1 bag of cement?
a bag of cement contains one cubic foot of cement...you will need 3 cu. ft. of gravel and 2 cu. ft. of sand per batch...
Q:Does anyone that had braces when they were younger still have cement on their teeth?
I still have cement on my back teeth and I've been to the dentist twice since I've had my braces removed. They scraped and scraped but I still think there's some left back there. The woman told me it would take several visits to get it all off. My orthodontist didn't really try that hard to get it all off. I don't think you have to worry about it though. Just make an appointment with your dentist and tell them you've still got some glue and they should try to scrape it all off if they can.
Q:how do u make home made cement?
cement bricks definitely. they are sturdier no matter what!
Q:mixture of water and cement?
The problems with cement is that it's a very Thirsty molecule. Could be all the water remains in the concrete. Concrete doesn't harden because it loses it's water - it hardens because of a chemical change (it's hot). Portland cement can harden under water - and the Romans understood this. Some of their bridges are still in use. Then the idea was lost until the end of the 18th century, I think.
Our company has our own research organization-cement and concrete research lab, which is fully equipped with up-to-date facilities. Our products have been exported to South Africa, Australia, the United Kingdom, Korea, the United Arab Emirates and Taiwan Area.
