The influences of superplasticizers, mixing time, mixing temperature and cement content on high-volume fly ash concrete were investigated in order to use the industrial by-product, fly ash from coal thermal power plant, more actively for concrete. The slump, air content, compressive strength and tensile strength of high-volume fly ash concrete were investigated using different mixtures.
The results of these investigations indicate that the properties of fly ash concrete are influenced by the type of superplasticizer and the use of naphthalene-based type superplasticizer is most suitable for this concrete. The slump and the air content of high-volume fly ash concrete are varied by the mixing time and mixing temperature. A three minute mixing time is best to obtain workable high-volume fly ash concrete in a pan-type mixer.
