The development of interlocking blocks from rubber latex mixed with degraded rubber tires, strengthened with palm fiber empty fibers from the agricultural industry

Abstract

The objective of this research is to study the engineering properties of normal interlocking blocks and interlocking mixed-block rubber bricks reinforced with palm bunch fiber. Which is divided into 3 ingredients ratio, ie 1: 3, 1: 5 and 1: 7, as the ratio of cement to dust stone In each ingredient ratio, rubber latex is replaced with 2% clean water, palm fiber, instead of 2% dust stone and debris that has been thoroughly crushed, instead of 2% dust. From the test found that Compressive strength of 1: 3 interlocking block bricks without replacement Obtained the highest average compressive strength of 354.39 kg / cm2 when using latex instead of 2% clean water, palm fiber filaments replaced 2% dust rocks and debris that deteriorated. Of average compressive strength of 40% in the ratio 1: 5 and 1: 7 without replacement Obtained the average compressive strength of 295.43 kg / cm2 and 208.37 kg / cm2, respectively, when using latex instead of 2% clean water, palm bunch fiber instead of 2% dust stone and debris that deteriorated the fine grinding of 2% dust. There is a decrease in compression strength 44% and 24%, respectively. From the bending resistance test of interlocking brick It was found that the ratio of 1: 7 in the form of rubber water instead of 2% clean water, palm bunch fiber replaced 2% dust stone and debris that deteriorated. Resulting in the best bending resistance And the determination of water absorption of interlocking brick blocks Found that the ratio of 1: 7 without latex Palm bunch fiber And scrap tires that are deteriorated, crushed Resulting in a minimum water absorption of 3.15% When applying the compressive strength of interlocking bricks Water absorption value of interlocking brick blocks To compare with the community product standards, Ministry of Industry Found that the interlocking block bricks mixed with rubber water instead of 2% clean water, palm bunch fibers replaced 2% dust rocks and debris rubber tires that had been crushed, replaced by 2% dust particles in all mixing ratios. Passed the Community Product Standards criteria, Chor. 602-2547, Ministry of Industry, designated and able to arrange the type of interlocking brick blocks in the type of interlocking block weight-bearing bricks And can be used in construction work.
