Agricultural wastes as aggregate in concrete mixtures – A review
The wide availability of agricultural wastes make them a suitable and dependable alternative for aggregate in concrete, wherever available. This paper reviews the possible use of agricultural wastes as aggregate in the concrete industry. It aims to promote the idea of using these wastes by elaborating upon their engineering properties.
Superplasticizers (SP's), also known as high range water reducers, are additives used in making high strength concrete.Plasticizers are chemical compounds that enable the production of concrete with ca. 15% less water content. Superplasticizers allow reduction in water content by 30% or more.

Ce6506 Ctep Notes Concrete Cement
Because most retarders also act as water reducers, they are frequently called water-reducing retarders. As per chemical admixture classification by ASTM-ASTM C 494, type B is simply a retarding admixture, while type D is both retarding and water reducing, resulting in concrete with greater compressive strength because of the lower water-cement

In order to reach high strength levels using a regular water reducer, the concrete composition had to be very carefully optimized and a stringent quality control programme had to be implemented. The idea was conceived to produce the highest possible compressive strength through lowering the water/binder ratio as much as possible. The cement was

Effect of Water-Cement Ratio: The effect of w/c ratio on the strength of concrete has been discussed in Sec. 10.4 and is shown in Fig. 10.13. The aim is generally to use the lowest watercement ratio which will give a concrete sufficiently plastic to place in position. Approximate relation of strength concrete with water-cement ratio is given by
