Abstract: Research on making composites from mixing limestone with addition of latex have been done. This study uses limestone originating from Sidikalang where crushed limestone using ball mill then calcined at 9000C for 2 hours then tested using XRD Pan Analytical X’pert Powder PW 30/40 to determine the presence of CaO compounds with the greatest intensity of 3036 at θ=37,3556 and particle size tested using PSA Shimadzu SALD-2300 is obtained an average of 731.7 nm. Then limestone powder (LSP) is used as a filler with various variations on latex composites. Analyzing of the morphology using SEM FEI Inspect-S50 can be seen from the photo that limestone powder can be evenly distributed on compsites 800 g of latex + 200 g of limestone powder while in the next variation the limestone powder is not evenly distributed because the addition of the filler increases but the addition of the matrix decreases. The mechanical properties of latex composites with limestone powder were tested using ASTM D-412 where optimum tensile strength was found in 800 g of latex + 200 g of limestone powder is 1,279 MPa and optimum elongation of 1000 g latex is 4,328 mm/mm. Thermal properties were tested using TGA ASTM E1131 obtained by decomposition thermal at 300-4000C because in the sample 1000 g of latex has thermal stability at 377,390C and in the sample 800 g of latex + 200 g of limestone powder has thermal stability at 378,210C.
