The FA used was similar to the class F fly ash designated by ASTM C618 , and the specific gravity was 2.27 with a fineness of 3381 cm 2 /g. For mixing water, tap water was used and a polycarboxylate-based superplasticizer was added as a chemical admixture.

Fundamentals of Concrete

represents a coarser material and a lower fineness modulus represents a finer material. Knowing the fineness modulus of aggregate gives you some indication of the amount of paste needed to make concrete using the aggregate. For instance, sand with a low fineness modulus has more voids in it and more particle surface, thus, more paste is

Cement vs Concrete Different Test, Type & Uses

7/16/2019 · While concrete is a mixture of many material like cement, sand, aggregate and water. Cement is used with other material while concrete is already mixed. Concrete is used for making RCC, DPC, PCC and filling many other holes of building, while cement is very thin paste so only used for concrete making or for making of cement plaster.


Cement is seldom used on its own, but rather to bind sand and gravel together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel , produces concrete . Concrete is the most widely used material in existence and is only behind water as the planet's most-consumed resource.
