    ADVANTAGES AND DISADVANTAGES OF PRESTRESSED CONCRETE ADVANTAGES : Use of high strength concrete and freedom from cracks‚ in prestressed members‚ contribute to improved durability under aggressive environmental conditions. The use of high strength concrete and high tensile steel in prestressed concrete members results in lighter and slender members than could be possible by using reinforced concrete and Mild steel as reinforcement. In prestressed concrete‚ steel is no longer required for reinforcement

    Non-destructive Testing Of Concrete By Rebound Hammer By Kaushal Kishore Materials Engineer‚ Roorkee INTRODUCTION The standard method of determining strength of hardened concrete consists of testing concrete cubes in compression. The quality of entire concrete of a structure cannot be fully assessed by testing a few concrete cubes. The results obtained in testing cubes do not always reflect the actual strength of concrete in construction. In a whole day‚ concreting work cubes are cast in

    Title : Concrete Cube Compressive Strength (7 days) Introduction : To determine the strength‚ maximum load can be applied and workability of concrete mixture. Theory : Hard concrete test were conducted at the age of 3‚ 7‚ 14‚ 21 and 28 days after curing(but we tested it for 7 days only). The concrete strength increases according to the age‚the mixture of its concrete design and the strength increment will continue for sometimes. Nevertheless‚ for most of the work‚ the concrete strength on

    Ingredients for concrete are cement‚ fine aggregate‚ coarse aggregate and water. The best concrete can be obtained by mixing the ingredients in correct proportions. The ideal proportion of concrete will be that‚ which produces greatest strength and solidity at the least cost. In estimating the quantities of ingredients for cement concrete it should keep in mind that voids of coarse aggregates are filled up by sand and voids of fine aggregates are filled up by cement. The concrete mix of 1: 1: 2 and
