In general, concrete is composed of cement, fine aggregate, coarse aggregate, water and additional substances if needed. But along with the development of science and technology, concrete constituent materials can also change or be combined with organic or inorganic materials such as plastic waste materials and others. HDPE Plastic (High-Density Polyethylene) Is a type of plastic that is usually used to make milk bottles, detergent bottles, shampoo bottles, moisturizing bottles, oil bottles with code No. 2., toys, and some plastic bags. PET (Polyethylene Terephthalate) PETE or PET is one of the plastics used for food containers, bottles of mineral water and several other wrappers. This plastic is designed for one-time use only. With the use of HDPE and PET plastic waste at a percentage of 20% for concrete compressive strength was not achieved, normal concrete = 15.88 concrete B.HDPE = 12.01, B.PET = 11.71, BC = 12.39 but for concrete weight decreasing, normal concrete = 2330 kg, m3 B.HDPE concrete = 2122 kg, m3, B.PET = 2128 kg, m3, BC = 2096 kg, m3. For the composition of the optimum concrete mixture of the three compositions (B.HDPE, B.PET, BC) obtained the composition of BC which has the most optimum value of 12.39 Mpa, but does not reach the compressive strength of the plan of 15 Mpa.

This study aims to determine the resistance of rice husk geopolymer mortars to sulfuric acid. This research was conducted using experimental methods, namely by conducting experiments in the laboratory. Cuboid specimens measuring 50x50x50 mm, using binder: fine aggregate ratio is 1: 1.5, activator: precursor ratio 1: 1 and the ratio of Na2SiO3 and NaOH is 2: 1. Mortar immersed for 20 days with immersion of 5%, 10% and 15% sulfuric acid concentration. The compressive strength of the free geopolymer mortar is 9.20 MPa, sulfuric acid soaked with geopolymer mortar with a concentration of 5% is 5.00 MPa, immersion with a concentration of 10% is 4.60 MPa and immersion with a concentration of 15% is 2.00 MPa. From the compressive strength test results showed that there is a decrease in compressive strength of mortar exposed to sulfuric acid, the more concentrated sulfuric acid concentration, the lower the results of the geopolymer mortar compressive test results. This can be seen in the compressive strength concentration value of 5% decreased by 45.65%, the concentration of compressive strength of 10% decreased by 50.00% and the concentration of compressive strength of 15% decreased to 78.26%.
