Strength of a clay soil and soil–cement mixture with resin

A series of laboratory experiments were carried out to investigate the effect of resin on the strength of a clay soil and soil–cement mixtures. One group of tests were carried out on samples of the clay soil that were prepared with different resin contents. Another group of tests were conducted on mixtures of soil–cement and soil–cement–resin with specified resin contents. The results show that adding more than 10% resin increases the strength of the soil, whereas at resin contents below 10% no significant effect was observed. The strengths of the samples of soil, soil–cement mixture and soil–cement–resin mixture increased with increasing percentages of cement and resin. The results also show that the increase in strength is a function of percentage of agents and curing time.
