Influence of fly ash on strength and sorption characteristics of cold-bonded fly ash aggregate concrete

A preliminary study on the effect of fine aggregate replacement with metakaolin on strength and abrasion resistance of concrete

“…The compressive strength increased as the content of FA increased. Joseph and Ramamurthy [8] investigated the compressive strength, water absorption and sorptivity of concretes containing sand replacement with FA. They used three cement contents of 250, 350 and 450 kg/m 3 , two ratios of coldbonded aggregate (CA) to total aggregate (TA) of 50% and 65% and two water contents of 175 and 220 kg/m 3 .…”

Utilization of cold bonded fly ash lightweight fine aggregates as a partial substitution of natural fine aggregate in self-compacting mortars

“…Coal-fired thermal power plants fabricate large quantities of fly ash (FA), but only a small amount can be used in concrete industry [1]. Utilization of industrial waste powder materials such as FA in production of artificial aggregate has attracted the attentions of investigators and practitioners as an alternative way for larger consumption [1][2][3][4][5][6][7][8][9][10][11]. Artificial aggregates can be obtained through processing of different materials and utilizing methods like cold bonding pelletization [1,[5][6][7][8][9][10][11].…”

Properties of cold bonded quarry dust coarse aggregates and its use in concrete

“…Manikandan and Ramamurthy [27] reported that the efficiency of pelletizing is influenced by the fineness of the fly ash. Joseph and Ramamurthy [28,29] found that cold bonded fly ash aggregates are suitable for the production of concrete having a compressive strength of up to 30 MPa. Gonzalez-Corrochano et al [30] reported that loose bulk and dry particle densities of artificial aggregate made using sludge of aggregate washing plant and fly ash are 1200 kg/m 3 and 2000 kg/m 3 , respectively.…”
