Abstract

Concrete Admixture is one ingredient of concrete that is added to the mix before or during mixing to modify the properties of fresh and hardened concrete in order to achieve the desired objectives or purpose of the concrete mixture. It is also used for economic purpose when admixture allows reduction of concrete ingredients proportions or permits saving in construction practices. The current research studied the effect of high temperature on the behavior of fresh and hard concrete is discussed and how to overcome that using some mineral admixtures such as silica fume and lime stone powder. An experimental test program consists of six concrete mixes was planned to achieve the research objectives, also all concrete mixes were tested at both of fresh and hardened state Fresh concrete testes include slump, slump losses, and air content. Hardened concrete tests include 15*15*15cm cubes for compression test at (3, 7 and 28days (, 15*15*70cm beams for flexural test at (28 days (and cylinders with 15cm diameter and 30 cm height at) 28 days), for tensile strength test. It was observed that from the results that: 1. Mix containing 1.5% s.p. &10% s.f gave best compressive strength results. 2. Mix containing 2% s.p. gave the lowest compressive strength results. Under the effect of hot weather.
