Comparison of Strong Pressure of Paving Block Using Sand Mix With Cement and Lime With Cement in Economic Event

Abstract

The use of paving blocks (concrete brick) is widely used for various construction elements of buildings, in the field work paving blocks are often used for pavement pavement roads, residential yards and public facilities, environmental roads and various other needs. The purpose of this study was to determine the comparison of normal paving block compressive strength tests with lime-based modified paving blocks originating from the Ngimbang area of Lamongan Regency, East Java. The test results obtained from the optimum value of the compressive strength test paving block modified limestone mixture ±50% as a substitute for sand aggregate obtained compressive strength value of 4.53 Nmm2 at the age of 7 days, while the optimum value obtained from the normal paving compressive strength test of 25.30 Nmm2 at the age of 7 days. From the results obtained there was a drastic decrease in compressive strength in the mixture reached ±20% . HaThis study shows that the manufacture of paving blocks using limestone as a substitute for sand aggregates does not meet SNI paving blocks. However, in general, economic modification of paving blocks is cheaper than normal paving blocks.
