Performance evaluation of cement stabilized fly ash-GBFS mixes as a highway construction material.
Fly ash and granulated blast furnace slag (GBFS) are major by-products of thermal and steel plants, respectively. These materials often cause disposal problems and environmental pollution. Detailed laboratory investigations were carried out on cement stabilized fly ash-(GBFS) mixes in order to find out its suitability for road embankments, and for base and sub-base courses of highway pavements....
متن کاملAn Experimental Study on Utilization of Slag and Fly Ash as an Alternative Cementitious Binder
This study investigates the utilization of slag and fly ash (FA) as alternative cementitious binder. Combination of 60% slag and 40% FA was used as new binder. In addition, for activation of slag and FA, sodium hydroxide and calcium hydroxide was used as a chemical activator by 5% weight of the binder, separately. Water to binder and sand to binder ratios was kept 0.55 and 3 in mortar preparati...
متن کاملEffect of Cement-fly Ash Additive on Compaction and Strength of Reservoir Dredged Material
Tremendous quantities of reservoir deposited sediments are required to be dredged regularly to maintain the storage capacity of the reservoir. The reservoir dredged material (RDM) can be utilized as construction material after admixing with additives such as cement and fly ash thereby improving its strength characteristics. This research paper presents results of laboratory investigation carrie...
متن کاملThe Performance of Fly Ash as Fill Material for Embankment Model on Soft Soil
Fly ash is one of coal ashes resulted from power plants using coal to generate electricity. As a result of large utilization of coal, large volumes of coal ash produced as waste material. Direct use of these materials in construction projects, not only provides a promising solution to the disposal problem, but also as an alternative for structural fills material. High shear strength, low compre...
متن کاملInfluence of High Temperatures on Flexural Strength of Foamed Concrete Containing Fly Ash and Polypropylene Fiber
In this study, the elevated temperature flexural strengths of lightweight foamed concrete (LFC) containing fly ash (FA) and polypropylene fiber (PF) was investigated experimentally and statistically. The variables included were the temperature degrees (in a range of 20 to 600°C), LFC densities of 600, 800, 1000, 1200 and 1400 kg/m3 and additive content. Two mixes were made by replacing 15% and ...
