In construction field there are a lot of complex works that require time andudskilled worker to handle the work. Interlocking blocks is a new method of constructionudwhere it gives a lot of advantages such as the reduction of unskilled workers, lessudwastage, less volume of building materials, increased environmental and constructionudsite cleanliness and better quality control. The aims of the research are to determine theudcompressive strength, abrasion and water absorption of the interlocking block b'yuddifferent proportion of cement added to the aggregate. Secondly to determine the effectudof alkaline solution to the compressive strength. This research was also to determine theudbest curing method to the interlocking blocks. Six different sets of blocks were carriedudout in this study. Interlocking blocks can be tested with various types of tests regardingudthe block's characteristic such as compression test, abrasion test and water absorptionudtest. However the optimum mix proportion between cement, sand and laterite forudcompressive strength 7.0 N/mm2 load bearing wall is not determined yet. Fromudprevious research that had been done, various type of curing had been applied to theudblocks but the results are uncertain. This leads to best way of curing is still unknown.udThe result for this research is divided into 3 category which are curing set, differentudratio trial set and lastly the alkaline solution set. For the curing set, the'variables wereudcuring under sun and curing under shade. For curing under sun, the result ofudcompressive strength was 3.96 Mpa and under the shade was 2.12 Mpa. The next isuddifferent ratio trial set where the variables are 1:1:6 and 1:0.5:6. For ratio 1:1:6 the udcompressive strength wasud5.63 Mpa and for 1:0.5:6 was 319 Mpa. Lastly is theudalkaline solution set where the variables were 1 molarity and 2 molarity alkalineudsolution. For 1 molarity alkaline solution the compressive strength was 5.31 Mpa andudfor the 2 molarity alkaline solution wasud5.40.udThe variables recorded that had theudstrongest compressive strength was the ratio of 1:1:6.
