Stabilization Of Laterite With Rubber Latex

Air pollution and the emission of greenhouse gases related to the manufacture of clinker for the manufacture of cement leads to consider the use of a natural binder other than cement for the stabilization of laterite. This laterite-rubber is a new sustainable material for construction and building. In this work a study on the amount of ammonia to delay the coagulation of latex for use as a stabilizer was conducted. In addition tests of water resistance absorption and mechanical tests were carried out on this new material to define its properties. 3 ammonia was used to delay coagulation of the latex. 0 to 30 latex content was used to stabilize laterite specimens. The tests carried out on these different test pieces gave the following results 15 latex specimens dissolve completely in water while 20 test specimens dissolve completely in water 25 and 30 are water resistant. The absorption rate decreases as the latex content increases in the test pieces. t goes from 1445 for the specimens to 15 to 5.87 for the 30 test pieces. The compression test shows an increase in resistance from 0.37 MPa for latex-free specimens to 3.15 MPa for 30 latex specimens. Also the study of the mechanical properties rheological behavior shows that the specimens have a plastic behavior when the latex content increases.
