Non-autoclaved aerated concrete made of modified binding composition containing supplementary cementitious materials

Abstract

In this paper the impact of carbonate-containing and sulfate components, zeolite, polypropylene fibers on the properties of modified binding composition and non-autoclaved aerated concrete based on them is investigated. The aerated concrete based on the modified binding composition containing a supplementary cementitious material, that of carbonate-containing salt waste, reinforced with polypropylene fibers is characterized by the compressive strength of 2.7 MPa with the density of 650 kg/m3. The thickness of partitions between pores is 0.16 – 0.21 mm, and the number of pores with the size 0.2-1.0 mm is 76.4%.

Review of selected aspects of shaping of physical, mechanical and thermal properties and manufacturing technology of lightweight and ultra-lightweight autoclaved aerated concrete

“…One of the effective building materials is light and ultralight aerated concrete based on non-organic binders [2][3][4][5][6]. Gunasekaran et al [7] note that the thermal resistance requirements for wall constructions are becoming increasingly stringent every year.…”

Utilization of Construction and Demolition Waste Along with Fly Ash waste in Preparing Non-Autoclaved Aerated Concrete

“…NAAC has several beneficial possessions such as low thermal conductivity, fire resistance, good sound insulator & water absorption [33]. Generally, the difference between Autoclave aerated concrete and non-Autoclave aerated concrete based on their curing method [28,34]. as compared with Autoclaved aerated concrete Nonautoclaved aerated concrete efficiently manufactured it does not need high pressure & steam for curing; it can quickly cure under 80C-100C for 2 to 6 hours, resultant less energy consumption saves the massive cost of production & This study also beneficial for those countries which have energy crisis issues, This aims of the study is utilization construction demolition waste & Fly ash waste in the manufacturing of Non-autoclave aerated concrete which widely available vast quantity in china, while fly ash is a substitute of siliceous materials, e.g., quartz sand.…”
