Environmental impact assessment of fly ash and silica
2020年5月1日 Fly ash–silica fume geopolymer concrete activated without sodium silicate has lowest environmental impacts. Transportation of raw materials is found to increase the overall negative of all four concrete mixes. Cost reduction of 10.87%–17.77% per unit volume is achieved with the use of fly ash silica fume based geopolymer concrete.
Effects Of Fly Ash And Silica Fume On Alkalinity, Strength
1 The present study examined the effects of Fly Ash (FA) and Silica Fume (SF) on the alkalinity, strength and planting properties of VPC. Since the Coarse Aggregate Size Ratio (CASR) has a substantial impact on the VPC strength, the current-study also examines the influence of CASR on the void content, strength and planting properties of VPC.
Development of construction materials from the
The maximum compressive strength of the geopolymer products GP-RFL was achieved to be 15.92 N/mm2 having water absorption of 10.47 % and bulk density 2.81 g/cm3. These results indicated that geopolymer mortars made from red clay, coal fly ash and lime could be used as an alternative construction material./p> BIBECHANA 19 (2022) 119-126. Keywords
