Rubber Latex Fiber Reinforced Concrete Solution to Many Construction Problems

Abstract

Rubber Latex Fiber Reinforced Concrete Solution To Many Copnstruction Problems The strength of the specimen was further tested by mixing 5%, 7.5%, 10% and 12.5% water in the pre-vulcanized latex to prepare the solution.

This study focuses on improving the engineering properties of laterite soil by using type 1 portland cement and pre-vulcanized latex. To prepare the improved specimen, laterite soil was mixed with cement and water in the ratio of 5:2:0.7 by weight.

The strength test was perfected for dry cured specimen on 3rd, 7th and 28th day. The best soil cement absorption of rubber latex and water mixture was also tested.

For an improved mixture with 6.23 percent average water absorption, 84 ksc compressive strength, 19 ksc tensile strength and 8.75 ksc flexural strength were obtained on the 28th day. Improvement of soil cement with 7.5 percent of pre-vulcanized latex and water solution thus yields the best results. This research therefore applied pre-vulcanized latex, soil cement, and concrete to construct drought relieving water pond.

Two ponds were built on the field using farmers ‘ participation: soil cement mix pre-vulcanized latex and concrete mixed pre-vulcanized latex. Both ponds were tested for water in the field and showed satisfactory results. During the drought season, farmers can take advantage of water saved in the pool.

Conclusion

Based on the tests results which are obtained, following conclusions are made:

  • Glass fibre helps concrete to increase compressive strength until indicated limit. A limit exists to a particular percentage from glass fibre mixed with concrete because increasing it affects on the bond of materials as is seen in the result. For 1.5% of cementitous weight gained best results are obtained as compared to other results.
  • By using 20 mm of coarse aggregate more air entraining is increased in the concrete:- only 10 mm coarse aggregate should be used to solve problem of reduced flexural strength.
