| The use of high strength concrete in building systems is increased all over the world. This research presents the production of high strength concrete using local materials available in north Sinai area. All concrete ingredients (cement, water, fine and coarse aggregates in addition to admixtures) were subject to the requirements of the Egyptian standard specifications. Compressive strength, indirect tensile strength, flexural strength, and permeability tests were conducted on the concrete. In this research, 27 concrete mixes were made with cement content 400,450 and 500 Kg/ m³. One type of Beir El-bd sand is used as fine aggregate and three types of coarse aggregates basalt, dolomite and gravel are used in high strength concrete mixtures. Silica fume was used with a dosage of (0, 10, 15) % of cement content, and also high water range reducer superplasticizer with a dosage of (0 and 3) % of the binder content. To achieve compressive strength greater than 500 kg/cm² at the age of 28 days. As a result, concrete mix containing a dolomite 15% silica fume with 3% superplasticizer produced a compressive strength of 950 kg/cm² and low permeability of 1.6x10 ֿ 9 cm³/sec. The use of lower amount of cement content, silica fume and superplasticizer gives lower strength and high permeability. Analyzing the results of this research produce a design that describes compressive strength-silica fume relationship curves and compressive strength-superplasticizer content relationship. | ||
