Agricultural wastes as aggregate in concrete mixtures A
The use of OPS as a lightweight aggregate for producing lightweight concrete was explored as early as 1984 by Abdullah [20] in Malaysia and by Okafor [16] in Nigeria. In most cases, it has been shown that the compressive strength of OPS lightweight concrete, with and without cementitious materials, is within the typical compressive Gneiss coarse aggregate and three types of fine aggregates as limestone, original WSFA (Weathered Steel Slag Fine Aggregate) and modified WSFA were used.

Experimental Study on Strength Gaining Characteristics
A suitable gradation of an aggregate in PCC and OPC mixture is important in order to secure strength gain of the concrete mix (Celik et al ., 2008; Sharifi, 2012).Despite reports that construction waste constitutes a large portion of solid waste in Malaysia [9], [10], the level of awareness toward recycling in production or application of recycled aggregates is still generally low [11]. natural crushed limestone (natural coarse aggregate (NCA)) and a polymer impregnation level of 0.05 wt% of theEngineering properties of treated recycled concrete aggregate (RCA

Materials Free Full-Text Effect of Size of Coarse Aggregate
Geopolymer binders are a promising alternative to ordinary Portland cement (OPC) because they can significantly reduce CO2 emissions. However, to apply geopolymer in concrete, it is critical to understand the compatibility between the coarse aggregate and the geopolymer binder. Experimental studies were conducted to explore Cement. Ordinary Portland Cement (OPC) Type I was used to prepare all the mixes. The utilised cement complies with the BS EN 197–1:2011(Citation 2011) standard for class 42.5 N and is produced by the UltraTech Cement Factory in the UAE.Table 1 displays the chemical composition of the cement.

Symmetry Free Full-Text Classification of Coarse Aggregate
Traditional aggregate particle size detection mainly relies on manual batch sieving, which is time-consuming and inefficiency. To achieve rapid automatic detection of aggregate particle sizes, a mechanical symmetric classification model of coarse aggregate particle size, based on a deep residual network, is proposed in this paper. First, The mining industry manages large volumes of tailings, sludge, and residues that represent a huge environmental issue. This fact has prompted research into valorization of these wastes as alternative aggregates for concrete production, embankments, pavement material, etc. The use of mining wastes as a resource for Mining Wastes as Road Construction Material: A Review
