Concrete Design & Production - Portland Cement Association

The paste, comprised of cement and water, binds the aggregates (usually sand and gravel or crushed stone) into a rocklike mass as the paste hardens. A properly proportioned concrete mix possesses acceptable workability of the freshly mixed concrete and durability, strength, and uniform appearance of the hardened concrete while being economical.

Cementitious Materials

GGBS is a useful by-product recovered from the blast-furnaces used in the production of iron. It can be used un-ground as a coarse aggregate or as a supplementary cementitious material (where it can replace up to 70% of cement in a concrete mix). Fly ash is a useful by-product of coal-fired power stations and is environmentally beneficial.

Waste Materials Used in Concrete Manufacturing | ScienceDirect

Can Lime Be Replaced?| Concrete Construction Magazine

Suggesting that these materials are equivalent to cement-lime mortars as defined by ASTM C 270 seriously undermines the intent and assurance provided by that standard. If a product is to be a replacement, it should perform equal to or better than what it is replacing. To date, nothing surpasses the performance of lime in masonry mortar.

Which of the following cement replacement material is ...

As the manufacture of one tonne of cement generates about 1 tonne of carbon dioxide, the environment could be conserved by using less cement through partial replacement of PFA and GGBS. On the other hand, the use of GGBS and PFA as partial replacement of cement enhances the long-term durability of concrete in terms of resistance to chloride ...

Concrete without Cement - A Green Alternative Fly Ash

Concrete without cement is possible with the use of fly ash as an alternate for cement. It matches both the chemical and physical properties of cement. Thus it has the ability to replace cement completely. The word "concrete" defines as the bonding between aggregates, cement and water ...

result is less production of acceptable grades of fly ash for concrete producers. Other materials can replace fly ash in concrete. The most notable material is blast furnace slag. It is cementitious and pozzolanic, thus, an excellent replacement for fly ash. It suffers from a somewhat limited supply situation also, and usually at an increased cost.

About Cement & Concrete : GCCA

Cement's central use is to bind together the ingredients of concrete – sand and aggregates. Cement is a glue, acting as a hydraulic binder, meaning it hardens when water is added. Cement itself is a fine powder that is made by first crushing and then heating limestone or chalk, with a few other natural materials, including clay or shale, added.
