The compressive strength of the AAC mortar was increased with the increase of CAC dosage when the CAC content was lower than 10%. But further increase of the CAC content decreased the strength of the alkali-activated mortar due to the formation of zeolite and katoite loosening the ...
two important stages of behaviour were observed. The first stage was a linear branch with a steep slope, which is related to the un-cracked condition of the beam. This stage occurred when the cracking load was obtained, and a drop in the slope was observed due to the progressive cracking...
Waste glass cullet (GC) was used to replace natural aggregates and waste glass powder (GP) was used to partially replace conventional precursors such as ground blast furnace slag (GGBS). Optimization was conducted innovatively aiming at maximizing the total waste glass content in the AAC materials...
The maximum compressive (59.21MPa), split-tensile (6.60MPa), and flexural strength (5.70MPa) results were obtained with a mixture of 55% GGBS, 35% WGP, and 10% MK in an 8M NaOH solution. The prosed work emphasizes the viability of incorporating optimum substitution levels of WGP (35%) ...
Results revealed that with increasing GGBS content, the AAms deteriorate after exposure to elevated temperature owing to dehydration causing mass loss, and weakening binder- aggregate bonding, which in turn decreased residual compressive strength. The efficacy of WG on the thermal behavior and ...
All the mixes had the same binder content and w/b = 0.48. This paper presents the results of the durability related tests that were carried out which included, chloride penetration resistance, porosity, carbonation, and alkali鈥搒ilica reaction. The effect of the different parameters including ...
The experimental results indicated that superior performance was achieved by using a ternary binder prepared with ISSA, GP, and GGBS under biogenic acid simulation. Such enhanced durability can be attributed to the low Ca content in the resulting alkali-activated gels, which also reduced the grain ...
This was, however, not observed in Class F fly ash due to low calcium content of Class F fly ash.doi:10.1016/j.jclepro.2020.122970Yiyuan ZhangRui XiaoXi JiangWenkai LiBaoshan HuangJournal of Cleaner Production
Waste glass may be used in concrete provided that the potential deleterious expansion caused by alkali-silica reaction (ASR) could be mitigated. In this study, the influence of glass content, color and particle size on ASR expansion of mortar was determined by the accelerated mortar bar method....
It was found the ASR expansion increased with the increase of GP content and the addition of CAC as the replacement of GGBS could significantly reduce the ASR expansion. The drying shrinkage increased with the increase of GGBS contents. The residual strength coefficient of the mortars after high ...
