Determination of physical and mechanical properties of cellular lightweight concrete

In recent years, especially in terms of thermal insulation and unit weight, the usage area of cellular lightweight concrete, which has considerable advantages compared to normal concrete, has started to become widespread day by day. The reasons for these materials are the lightness and low heat transmission coefficient, and the material is a natural and local material. Within the scope of the thesis, many experiments have been carried out to reduce the unit weight of cellular lightweight concrete, which is the inorganic insulating material with cement bonding, to the lowest levels and to give the highest insulation property. As a result of these experiments, the most appropriate samples were obtained. It has been observed that the dry unit density has the lowest density with 139 kg / m3 and the thermal conductivity value of this sample has the lowest thermal conductivity value with the value of 0.0398 mW/mK. Pressure and tensile strength of these samples were obtained by mechanical experiments. The pressure strengths are min. 4.66 MPa. Tensile strength is max. 0.921 MPa. The ultrasonic sound tests of the samples were made and it was found that the samples with low sample densities had low speed transmissions. Ultrasonic speeds min. 550 m/s while max. 2604 m/s. Water absorption tests of the samples were made and water absorption rates of 200% were observed in some samples where the water absorption rates of the samples were very high. Water absorption percentage min 37.19%, max. % 199.20. Samples with low water absorption rates were generally more successful in the freeze-thaw test.
