Soil-cement mixture properties and design
soil-cement is a mixture produced by grouting or mixing cement with soils. This paper reviews and discusses the general classifications of grouting techniques and the suitability of their applications. The mechanical properties of soil-cement mixture and the influence of sodium silicate added are discussed.
Cement
The cement in soil-cement continues to hydrate over a long period Of time even under traffic. Cores taken from roads after many years of use show appreciably greater strength than samples tested at 7 and 28 days (Fig. 3). This means that soil-cement has a reserve of strength to accommodate increases in volume and weight Of tra ffic.
