EXPERMENTAL WORK ON STRUCTURAL LIGHT WEIGHT CONCRETE USING PUMICE AS PARTIAL REPLECEMENT OF COARSE AGGREGATE
Concrete is a type of artificial stone which can be produced by a mixture of aggregate, water, and cement. There are various types of concrete can be found in the market due to the desired structural properties. Lightweight concrete (LWC) is one of the most important types of concrete owing to its unit weight and insulation properties against temperature and voice. Structural Lightweight aggregate concretes are widely incorporated in construction and development. This study, presents an experimental Work on the Structural Lightweight concrete by partial Replacement of Coarse Aggregate by volcanic pumice. For C-25 grade concrete by replacement weight percentages of 10, 20, 30 and 40%, Coarse Aggregate by volcanic pumice. The use of structural grade light weight concrete reduces the self-weight and helps to construct larger structural units. In our country there is the sacristy of land especially in large city. So we have to adopt the SLWC to construct high rise building for accommodation of money people in one place. For this purpose along with a Control Mix, 12 cubes 15cm*15cm*15cm size, sets were prepared. Slump test were carried out for each mix in the fresh state and also, 7days and 28-days Compressive strength, split tensile strength and Flexural tensile strength tests were performed in the hardened state. According to ACI 213 (SLWC) made with lightweight aggregate; the unit weight at 28 days is between 1440kg/m3 to1850 kg/m3 and the compressive strength is more than 17.2 MPa. So this study result will shows the compressive strength of 0%, 10%, 20%, 30% and 40% fulfills its requirements. But not for the density. In other word according to ASTEM C 496 and (ACI 318) the minimum splitting tensile strength of lightweight concrete is 2.0MPa so the outcomes of our study all of it fulfill its requirements.
