The effect of fly ash and silica fume on mechanical properties
It is presumably due to that the pore-filler effect of fly ash particles play a main role in concrete because of the lower activity than that of cement at the early curing days. For FA10, the pore-filler effect is less evident than the low hydration effect on the concrete, which causes the increase of large void, resulting in the increase of chloride Effects of silica fume and Fly ash on properties of mortar reinforced with recycled-polypropylene.

Effect of fly ash and silica fume on hydration rate of cement
The effect of fly ash and silica fume on hydration rate and strength of cement in the early stage was studied. Contrast test was applied to the complex cementitious system to investigate the hydration rate. Combined with mechanical strength, the influence of fly ash and silica fume during the hydration process of complex binder By considering the adverse environmental impacts of the cement manufacturing process, there have been many efforts for cement replacement by supplementary cementitious materials (SCMs), which can enhance the produced concrete performance while reducing cement consumption. This study evaluated the effects of Evaluation of Mechanical and Durability Properties of Eco

2. requirements that cannot always be achieved routinely using conventional constituents and normal mixing, placing, and curing practices”. To achieve economic advantages with sustainable construction techniques, HPC has fabulous popularities. Supplementary cementitious materials like silica fume (micro silica), fly The production of cement releases an enormous amount of CO<sub>2</sub> into the environment. Besides, industrial wastes like silica fume and fly ash need effective utilization to reduce their impacts on the environment.

Combined effect of silica fume and fly ash as cementitious
The mix containing 15% silica fume and 30% fly ash as cement replacement produced 234.568 KgCO 2 /m 3, a great reduction of 42.63% of embodied CO 2 emission as compared to control mix at 408.88 KgCO 2 /m 3. 5. With the substitution of cement with silica fume and coal fly ash, cost of AAC greatly reduced.Environmental problems associated with waste product disposal, resource conservation considerations, and the cost of portland cement will demand the increasing use of of fly ash, slag, condensed silica fume and rice-husk ash in the production of cement and ready-mixed and precast concretes.

Effect of Silica Fume and Fly Ash as Partial Replacement of Cement on
Cement manufacturing industries emits 5% of global carbon di-oxide which in turns leads to the main causes for the global warming. To decrease the effects we can change the cement with industrial by- product like silica fume, fly-ash and so on. Basically the Fly Ash and Silica Fumes are industrial by-products.Geopolymer concrete (GPC) is the alternative substitute of cement concrete. It can reduce global warming as well as solves the problems regarding industrial waste disposal. The main purpose of this study was to evaluate the mechanical properties of low-calcium fly ash-based GPC and silica fume blended GPC.
