The potential for capillary rise into the stabilized layer will also help assess whether or not diffusion of deleterious salts into the stabilized layer are probable. The Texas Department of Transportation (TxDOT) recommend continuous material sampling to a depth of at least 15 feet in locations where water fluctuations are high (11).

Varying proportions of cement, coarse sand (CS), and fine sand (FS) were used in a quest to find an optimum combination for producing CSEB that meet the design criteria outlined in several standards. Inclusion of 50%–60% CS is found to provide maximum density and compressive strength, and beyond 60% CS content, strength begins to drop.

Cement stabilization is especially useful in coarse-grained soils. What is Portland cement? Portland cement is the most common type of cement. Its basic components are calcium, silica, alumina, and iron derived from limestone, sand and clay. All are processed, fired in a kiln and pulverized to a fine powder.

ii Abstract: Cement-treated base (CTB) is a mixed-in-place or central-plant-produced material consisting of soil/aggregate, cement, and water that creates a strong and durable stabilized roadway base. This guide to CTB discusses its applications, benefits, design, construction, testing, and performance.
quality of hardened portland cement concrete, less is known about the sulfate resistance of cement stabilized soils. The resistance to sulfate attack differs for cement-treated coarse-grained and fine- grained soils and is a function of sulfate concentrations. Sulfate-clay reactions can cause deterioration of fine-grained soil-cement.

Soil-cement stabilization (SCS) is one of the commonest system of stabilizing soils which may possibly loose pre-eminence in the developed countries of the world due to cost and unsustainability, if a viable equivalent alternative is found. However, in developing countries like Nigeria, it is the major stabilization agent for flexible pavement in spite of large
Stabilisation with cement is an effective way to increase the stiffness of base and subbase layers and to improve the rutting of subgrade. The aim of the study is to investigate the effect of different percentages of cement additives (1.5%, 3.0%, 4.5% and 6.0%) on the resilient modulus of coarse-grained soil used on road foundations. The influence of the compaction method, the standard Proctor ...
Cement stabilised sand is sand that has been mixed with a low dose of cement and with a small amount of water so that it sets hard but not as hard as screed or concrete. It is often used by builders for projects such as: Filling around water pipes.
This research investigated the potential of cement stabilized shale quarry dust for possible use as road foundation material. From the results, the shale consists mainly of SiO 2 (27.7–60.1%), Al 2 O 3 (7.30–17.9%), CaO (3.91–32.3%) and LOI (4.93–18.8%).
