Limestone Modified Cement for High-Performance Concretes

Abstract

This paper presents laboratory test results of the use of limestone modified cement for high-performance concretes, namely: self-compacting high-performance concrete and vibrated high-performance concrete. The limestone modified cement consists of portland cement and milled limestone. The test results show that proper selections of fineness and content of milled limestone reduces water demand, drying shrinkage, superplasticizer dosage and portland cement content for mortars as well as for concrete. The use of limestone modified cement containing selected fineness and content of limestone also increases compressive strength of the high-performance concretes.
