Abstract

A potential use of superplasticizing admixture is to produce structural concrete of High-strength concrete,. By using a superplasticizer, more workable mixes can be achieved while permitting a high cement content and a low water/cement ratio both of which are necessary to obtain high strength by conventional manufacturing technique. In this study, therefore, high strength concrete having a 28-day strength in excess of 650kg/$\textrm{cm}^2$ can be obtained using a superplasticzer. However, before such a high strength concrete is recommended for use, engineering properties have to be assessed. This study is aimed to analyze and investigate the engineering properties, such as strength, elasticity, ultrasonic pulse velocity, rebound value of superplasticized concrete having a various cement content.
