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:Cement Board or Plaster Board in shower?
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:What's the best way to get unstuck from cement?
Why un-cement yourself? I think a stationary husband, cemented into the kitchen would be a lovely feature and a GREAT conversation point! Maybe you could cement the kids onto the front lawn.... real live garden gnomes! :)
Q:420 kg cement how many cubic feet?
wet or dry? assuming dry: But there are many unknowns, see below. I'll take a number of 1000 kg/m³ and you can change as needed 420 kg / 1000 kg/m³ = 0.4 m³, which converts to 14 ft³ Cement (finely ground gray or white powder used to bind concrete mixtures) weighs between 830 kg/m³ and 1650 kg/m³ depending on its handling. The weight of cement that has been pneumatically loaded into a cement silo may be as low as 830 kg/m³, while cement that has been stored for a period of time exposed to vibration may be as heavy as 1650 kg/m³.
Q:What is a good pair of shoes for working on a cement floor?
I worked at a home improvement store for over a year, with a cement floor. I bought some insoles at Walmart...I want to say they were about $8. Pretty sure they were Dr. Scholls, but not sure since it was so long ago. They were made of thick neoprene rubber...and they lasted me over a year that I worked there. I just slipped them into some Adidas shoes that I didn't mind getting dirty, and it saved my legs a lot of the shock that your feet take walking on such a hard floor...so look for these at less than ten bucks, and you can use just a good ol' pair of sneakers you already have! Good luck to you!! 0=)
Q:Installing cement board...?
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:when do we use cement and concrete?
Portland Cement is is the binding agent in making concrete. Concrete is made of cement, limestone, sand. You would not cement other than to mix up concrete. Mortar, a mixture of sand cement is used in brick walls.
Q:How does cement dry underwater?
it doesn't dry; it sets - it's a chemical reaction; not simply evaporating its water content. Setting time depends on the exact chemical mix of the cement - unsurprisingly, fast-drying cement sets very quickly but is usually comparatively brittle, while slower formulations take longer but tend to be stronger. Considerable heat is given off during the setting process and the cement tends to expand, particularly if too much is added at once so that the heat in the middle can't dissipate quickly enough - this is another reason why slow-setting is preferred in many situations. Setting is also speeded up by spraying with water which not only aids the chemical reaction but also helps in cooling. Under the sea the water would actually assist in the setting process. The main problem is that it will be subjected to the pressure of the escaping oil while setting which will reduce its strength - this is probably why they're also pumping mud into the hole - this will partially clog up the hole and reduce the pressure and so give the cement a better chance of working.
Q:what is cement ? this for a scince project we have to do this.?
Cement is ground up limestone. It has the properties of reacting to water and binding itself together
Q:can cement be extracted back from concrete?
No, wetting, setting and curing is a one way process.
Q:Does anyone that had braces when they were younger still have cement on their teeth?
Nope. i've got have been given had braces for over a month and after eating soda, now no longer some thing befell. no count if it somewhat is on your mouth, i'm useful it somewhat is not poisonous hun. i could propose now no longer eating soda as a lot, regardless of the indisputable certainty that, simply by certainty soda motives cavities easily and a hollow section with braces could in elementary words reason the orthodontist to could desire to save them on a lot a lot longer. it somewhat is greater useful to in elementary words drink water or yet yet another helthy dtink as nicely, as soda is somewhat volatile do to the severe fructose corn syrup and all the flexibility.
