Perencanaan Bata Beton (Paving Block) K-400 dengan Adiftif Bahan Plastik

Abstract

Developments in the construction sector today is marked by the increasing quality of building materials and the emergence of new building materials. Especially for road pavement materials, are now widely used rigid pavement (rigid pavement) one of which is paving block. This study aimed to obtain compositions suitable for manufacture of paving blocks with a mix of quality K-400 and compare the compressive strength of concrete by the addition of plastic material and shaped concrete paving blocks (size 10 cm x 20 cm x 6 cm). The research began with the calculation of the mix design so that the compotition of the concrete specimens was obtain. Which would then be through the curing process and compressive strength testing. From the research results, obtained mix design: cement (1): sand (1:51): gravel (2.18): water (0.45), and after testing, obtained an average compressive strength of K-393.9 kg / cm2. The addition of plastic material as much as 20% produces a decrease in the average compressive strength of 39.6% to 237, 6 kg / cm2. While normal concrete mix design that shaped paving block produces an average compressive strength of 526.1 kg / cm2, up 33%.
