“…Aerated (foamed) concrete was invented in the 1920's with properties that are advantageous for constructing buildings [26,27,28]: (a) typical compressive strength of 3.6 N/mm 2 means it can be used throughout multi-storey buildings, including solid walls, beam and block flooring systems, foundations, internal and external leaf of cavity walls, separation walls and partitions [17]; (b) highly thermally insulating; (c) porous structure allows for superior fire resistance; (d) workability allows accurate cutting; (e) non-toxic (no toxic gases or other toxic substances in autoclaved aerated concrete); (f) long lasting (it will not degrade under normal climate changes). Aerated cement blocks are "Semi-porous materials with open pores always include a certain percentage of moisture that affects their physical, thermal, and mechanical properties" [29].…”

“…It has been reported that the hydrothermal reactions in a CaO-SiO 2 system are controlled by the dissolution of quartz [4,5,6]. The influence of alternative SiO 2 sources, as well as various Al compounds, on phase formation under hydrothermal conditions has been studied by many researchers [7,8]. Kurama et al [7] examined the use of coal bottom ash as an aggregate to produce aerated concrete.…”

Kurama et al [7] examined the use of coal bottom ash as an aggregate to produce aerated concrete. Their findings indicated that the use of the coal bottom ash caused a decrease in the unit weight of the AAC produced using different bottom ash replacement ratios.…”

Stone powder sludge is a byproduct of the crushed aggregate industry, and most of it is dumped with soil in landfills. The disposal of stone powder sludge presents a major environmental problem. This paper investigates the effects of stone powder sludge on the fluidity, density, strength and micro-structure properties of AAC(autoclaved aerated concrete) samples. Stone powder sludge was obtained from a crushed aggregate factory in order to investigate its applicability as a substitute for quartz sand in AAC. To determine the properties of the AAC samples produced with stone powder sludge, specimens containing different foam ratios were produced. Flow value, density, compressive strength, tensile strength and flexural strength of the samples were tested, and X-ray diffraction (XRD) was performed. The test results indicated that the compressive strength of AAC specimens (F120) with stone powder sludge was higher than that of AAC specimens (Q120) with quartz sand for same foam ratio of 120%. For all XRD diagrams, a higher number of tobermorite peaks was shown for the F120 sample than for the Q120 sample, which may explain the slightly higher strength gain in the F120 sample.

“…The employment of superplasticizer helps in achieving flow-able concrete while the viscosity modifying admixture provide segregation resistance, reducing bleeding and maintaining homogeneity between constituent material. The additive materials from waste by-product such as fly ash, bottom ash, quarry dust, and silica fume also can be added to concrete as part of the total constituent system [2,3,4,5,6]. The benefits of these additive materials come from its particle size distribution characteristic and pozzolanic activity.…”

Self-compacting concrete which commonly abbrevited as SCC is a special concrete that have the ability to consilodate fully under its own self-weight without any internal or external vibration. This paper presents the experimental investigation carried out to study the strength of self-compacting concrete incorporating bottom ash at different replacement level of natural sand. The composite cement was used and the replacement level of bottom ash to natural sand is set up to 30% by volume. The strength properties such as compressive strength, split tensile strength and flexural strength of the concrete at the age of 7 and 28 days of curing day were conducted. Results shows that the strength of the concrete with bottom ash increased up to replacement level 15% higher than control specimens. This show that bottom ash can be used as supplimentary cementitious materials, having the pozzolanic reactivty.
