Abstract

Recently, self-compacted concrete is widely used in many engineering projects. In addition, high strength concrete is required for high-rise building in Egypt. Therefore, the objective of this work is to study the possibility of producing high-strength self-compacted concrete with the available materials in the Egyptian Market. The target compressive strength of 80 to 100 MPa is required with using the available aggregates in the area of Suez Canal Area at north east of Egypt. The constituent materials are tested and compared with the requirements of Egyptian Standard Specifications. Self-compacted concrete mixes are designed according to the European guidelines for self-compacted concrete. Several factors are studied including coarse aggregate contents and w/c ratio. Fresh concrete properties are measured with slump flow, T50, V-funnel, L-box U-box, and GTM tests. Compressive strength of produced concrete are measured at different ages up to 56 days. Two sizes of test specimens of 100x100x100 mm and 70x70x70mm are used. Three concrete cubes are cured in at temperature 100oC for 24 hours and tested at age of one day. However, other test specimens are cured in water at room temperature for 7, 28 and 56 days. Many trial mixes are carried out, and only four mixes are comply with the properties of self-compacted concrete from point of its flow-ability, pass-ability from reinforcement, and its resistance to segregation. An early compressive strength of 70 MPa are obtained after 7 days for some mixes and more than 100 MPa are reached at age of 56 days.
