Abstract | ||
This investigated is conducted to study the effect of adding of marble dust and polymer (Styrene Butadiene Rubber) on the properties of clay brick. Specimens manufactured from soil brought from ( al-Huda plant of brick) located in Hilla . The proportions of the components of this soil were (% 49,% 18,% 33) (Clay, Sand, Silt), respectively, marble dust and (SBR) were added with percentages (12, 24,36) for marble dust and (5, 10, 15) for( SBR) by weight of dry soil. The properties of brick product were studied in two case ,in the first percentage of addition ( water /soil) was (15) and the second was (27) , also studied the case of adding (SBR) without adding water with addition a constant percentage of (marble dust) for all proportions of (SBR ). All Specimens were burnt in the same ( al_Huda plant) at a temperature of (1000 ° C) after being dried natural for a period of (7 day), through practical results for all test observed that the marble dust and (SBR) when the (water / soil = 27%) have the negative effect for compressive strength but marble dust has the acceptable effect on properties (water absorption and efflorescence) . However when the ( w/s=15% ), the marble dust and ( SBR) have an obvious positive effect for all properties of clay brick especially at addition of marble dust in ( 36 percentage) and (15 percentage) for polymer (SBR). | ||
