Abstract :
One of the negative impacts of rapid development of physical development is the exploitation of natural resources (NR). Natural Resources in question is one of the raw materials for building materials ie sand. One alternative to reduce the exploitation of natural resources is to utilize waste shells as raw material manufacturing of paving blocks. Utilization of waste shells are very less, as long as it is only used as decoration, animal feed and cosmetics Mixed. The purpose of this study to determine the value of test Compressive Strength, Water Absorption, and Absorption of Sodium Sulfate. Decision taken of shells in the village Kalanganyar Sedati, Sidoarjo. The raw material mixture of sand and waste shells. Comparison of the composition of the waste sand and shells are 100%: 0%, 90%: 10%, 80%: 20%. The raw material is mixed with a cement binder with a 1:4 ratio of Aggregate. Furthermore, printed and press the mixture with 20kg/cm2 pressure, then do a physical exam to determine the best quality according to standard paving block SNI 03-0691-1996. The experimental results show that the best results from testing water absorption and compressive strength test of paving blocks can be achieved at the ratio of 80% sand, shells 20% by age 28 days paving block. In this composition has a moisture content of paving block 2.94% and 46.79 MPa press kut test that meets SNI 03-0691-1996. For best results from the absorption of sodium sulphate test can be achieved at the ratio of 100% sand, seashells 0% by age 28 days paving block. In this composition paving block absorption of sodium sulfate has a bit so it is not easily fragile that meet SNI 03- 0691-1996 with a yield of 0.05% which meets PP. 85, 1999. Keywords: Waste seashells, sand, paving blocks, compressive strength, water absorption, the absorption of sodium sulfate,.
