|dc.description.abstract||This research aims to study the waste concrete interlocking blocks . That is appropriate for use in construction or not . By comparing the block integration in general. The ratio of cement dust Rocky was 1: 5 , 1: 7 and 1: 8 by weight tested after compressing the period of 3 days, 7 days, 14 days and 28 days to study the compressive strength at the time were . and the engineering properties of various interlocking blocks.
The study found that co- produced blocks of stone dust has the ability to absorb compressive strength, dry density and thermal wear . Values are in the acceptable criteria . Compared to the typical block coordinate basis coordinate Mผch blog community standards . 602-2547 Ministry of Industry. By mixing cement with concrete ingredients first . Equals ( 1: 5 ), the compressive strength average maximum 105.58 ksc at 28 days , the rate of cement dust Rocky ingredients 2. Equal (1: 7 ) have compression . 87.37 ksc average maximum at 28 days , concrete mixture ratio of cement to three . equal (1: 8 ) has the highest average 82.12 ksc compressive strength at 28 days of standard production . Standard Blogging Community Coordinator Mผch . 602-2547 Ministry criteria . Interlocking block compressive strength equal to 70 ksc. Therefore conclude that rock dust can be used to produce interlocking blocks very well in all the ingredients , so that the introduction of waste into value added . Reduce waste and reduce environmental impact is another way.||en_US
