Abstract
This research focus on improving engineering properties of laterite soil using Portland cement type 1 and pre-vulcanized latex. Laterite soil was mixed with cement, and water in the ratio of 5 : 2 : 1 by weight to prepare the improved specimen. Strength of the specimen was further tested by mixing water in the pre-vulcanized latex in different proportions of 5%, 7.5%, 10% and 12.5% to prepare the solution. The strength test was performed on 28th day for dry cured specimen. Best absorption of rubber latex and water mixture by soil cement was also tested. The results show that soil-cement, 7.5%
pre-vulcanized latex solution and water when mixed in the proportion of 5 : 2 : 1 gives the best 2 performance. 84 ksc compressive strength, 19 ksc tensile strength and 8.75 ksc flexural strength was obtained on 28th day for the improved mixture with 6.23% average water absorption. Thus, improvement of soil-cement with 7.5% of pre- vulcanized latex and water solution gives the best results. Therefore, this research applied pre-vulcanized latex, soil cement to construct drought relieving water pond. A pond was constructed on the field with farmer’s participation using; the pond was tested for water seepage in the field and showed satisfactory results. Farmers can take advantage of water saved in the pool during the drought season.
