Abstract

This paper is part of a preliminary investigation on the use of a new generation of water-reducing chemical admixture. Ten concrete mixes were produced for various amounts of water-reducing admixture (AD) dosages ranging from 0 - 0.7% (by mass of cement) with W/C of 0.28, 0.34, and 0.38. Workability of fresh concrete was investigated. Cylinder concrete specimens were made for evaluation of compressive strength, ultrasonic pulse velocity (V), and dynamic modulus of elasticity (E d). Prism concrete specimens were made for evaluation of length change. Tests were conducted at 1, 7, 28, and 56 days. Generally all mixes containing AD achieved higher strength than the control mix without AD. The presence of AD caused a reduction in shrinkage. Correlations between the various properties were also attempted. Recommendations for using a higher dosage of AD and different mix proportions were proposed.
