Considering the increasing trend of using lightweight concrete in the world due to the efficiency of building style and therefore the reduction of rain and earthquake forces on structures, as well as cost and space saving as well as better thermal insulation performance As a result, energy saving energy; the need for light concrete production with a relatively high resistance and also suitable for identification.
This research project is the result of a laboratory and theoretical study of a special type of light aggregate called leka and the addition of a lubricant based on Nafalin SN (150); in this research, concrete has been studied in terms of the composition of the compatibility scheme and chemical additives; Thus, four main liquid designs were tested for different cement content and a different percentage of lubricant was added to 1.5, 0.61 and 1.8 percent by weight of cement. The results indicated that the highest compressive strength Compared to all the samples and designs related to the high-performance lubricant 1 with a high lubricant, SN1 / 8% with a resistance of 23 MP, and in designs 3 and 4, compared to the control plan K Resistance resistivity and in the 2-resistivity test, with the highest lubricant, SN1 / 5% is the best resistance to pressure in the design of 1 with a resistance of 20 MPa. In each design, resistance has increased in comparison with the control plan. With the highest lubricant, SN1 / 65% had the best compressive strength, with a resistance of 8.28 MPa, and all the designs with a slight increase in strength
