The effects of the aggregates characteristics on the performance of Portland cement concrete
Aggregate shape, texture, and grading have a significant effect on the performance of fresh concrete. Aggregates blends with well-shaped, rounded, and smooth particles require less paste for a given slump than blends with ...
An Experimental Study on the Guidelines for Using Higher Contents of Aggregate Microfines in Portland Cement Concrete
The use of manufactured fine aggregate (MFA) in portland cement concrete becomes more common as sources of natural sands are depleted. There is a great need to utilize MFA better, particularly the minus 75µm sizes. The ...
Alkali-Silica Reaction in Portland Cement Concrete: Testing Methods and Mitigation Alternatives
Identifying the susceptibility of an aggregate to alkali-silica reaction (ASR) before using it in concrete is one of the most efficient practices for preventing damage and failure. Several tests have been developed for ...
Framework for Development of a Classification Procedure for Use of Aggregate Fines in Concrete
Although data on use of aggregate fines in portland cement concrete are largely very encouraging, there is a lack of proper definition, and knowledge regarding nature, and characteristics of different aggregate fines, their ...
