Compressive strength of Sand mixed Grout for Low Volume Roads

Abstract

The composition of the solution was developed on the basis of criteria for fresh starches and carbide properties. Different doses of high-pressure water reducers (0%, 0.2%, 0.4%, 0.5%, 0.7%) and silica impurities (SF) (0%, 2%, 4%) (as a replacement of cement by weight). Then, further development focused only on the best grout compositions. In addition, the use of waste materials can contribute to the resolution of environmental problems. The presented study represents the results of an experimental study handled with specimen made of different sizes of aggregate and grout. These experimental studies cover the characteristics of grout such as compressive strength, bleeding, setting time and viscosity for different curing times. Specimen was prepared of two size of aggregate with same water/cement ratio. We have replaced concrete with grout to find out different compressive strength as compared to concrete specimen. The result showed us that 12.5 mm size of aggregate gains more compressive strength as compared to aggregate size 10mm after curing period of 7 and 14 days.
