Book Description
On-going research at Texas A & M University indicated that soil stabilization using calcium chloride filter cake along with Class F fly ash generates high strength. Previous studies were conducted with samples containing calcium chloride filter cake and both Class C fly ash and Class F fly ash. Mix design was fixed at 1.3% and 1.7%calcium chloride and 5% and 10% fly ash with crushed limestone base material. Throughout previous studies, recommended mix design was 1.7% calcium chloride filter cake with 10% Class F fly ash in crushed limestone base because Class F fly ash generates early high and durable strength. This research paper focused on the strength increase initiated by greater than 1.7% pure calcium chloride used with Class F fly ash in soil to verify the effectiveness and optimum ratio of calcium chloride and Class F fly ash in soil stabilization. Mix design was programmed at pure calcium chloride concentrations at 0% to 6% and Class F fly ash at 10 to 15%. Laboratory tests showed samples containing any calcium chloride concentration from 2% to 6% and Class F fly ash content from 10% to 15% obtained high early strength however, optimum moisture content, different mix design, and mineralogy deposit analysis are recommended to evaluate the role and the effectiveness of calcium chloride in soil stabilization because of the strength decreasing tendency of the samples containing calcium chloride after 56 days.

Book Description
Paper 1: Properties of loess soils are studied for an understanding of stabilization involving cementing reactions. Mechanical analyses were performed on four loess samples by hydrometer and pipette methods. Paper 2: The effects of calcium chloride under different moisture conditions and compactive efforts were observed by experimentation in stabilization of a bank-run gravel with calcium chloride. Paper 3: A laboratory investigation is described of the following variables involved in mixing Portland cement into a clayey silt: uniformity of soil and cement mixture, compressive strength of the resultant soil-cement, time of mixing, and accumulative energy required for mixing.

Book Description
A laboratory study was conducted to determine the feasibility of stabilizing an organic silt for use in sub-base or base courses for all-weather, low-volume roads and airfields in Alaska. The soil used in this study has an organic content of 12% and a modified Proctor value of 79.1 lb/cubic foot at a 29% moisture content. The stabilizers evaluated were: cement, cement with additives (calcium chloride, hydrogen peroxide, sodium sulfate, and lime), lime, lime/fly ash, asphalt emulsion, tetrasodium polyphosphate, and calcium acrylate. Unconfined compressive strengths obtained were: 39 lb/square inch with 20% cement, 64 lb/square inch with 20% cement and 2% calcium chloride, 51 lb/square inch with asphalt emulsion, and 348 lb/square inch with calcium chloride. Lime and lime/fly ash proved to be ineffective for this soil. Although tetrasodium polyphosphate did not improve the soil's strength it did reduce frost susceptibility and permeability. Keywords: Chemical stabilizers, Organic soils, Soil stabilization.
