The lmpact of Degree of finess send on The Density and Compressive Strength of Thermeston

Abstract

The light weigh concrete (Thermiston) have wide uses in the recent building and structures . Mixing (Cement , lime , Sand) together with Aluminum powder have been create the thermiston material. This paper study to find out the impact of the fineness of sand on both of the density and the compressive strength for the thermiston material . this study was used six degree of sand (48 , 52 , 58 , 60 , 64 , 68) to get (36) samples which crated a cubical shape (100×100×100) mm3 ، six samples from each degree.The laboratory examination indicated that the density is between (0.69 - 0.75) g /cm3 and the compressive strength is between (0.40 - 8.21) N /mm2 .The final results ensured that There is no effect for the finesse of sand on thermistons density , but there is effect on compressive strength , whenever more finesse degree of sand more compressive strength
