Benefits of using blended waste coarse lightweight aggregates in structural lightweight aggregate concrete

Optimum Oil Palm Shell Content as Coarse Aggregate in Concrete Based on Mechanical and Durability Properties

“…Obtained results show that the 28-day compressive strengths of all concretes containing OPS are comparable with structural LWC. Reduction on the compressive strength of OPS concrete is due to smooth surface texture of the OPS aggregates which resulted weaker interfacial zone [19,33,34]. Mannan et al [33] investigated the compressive strength of OPSC.…”

Ecologically Safe and Techno Economically Efficient Reinforced Concrete Constructions of Equal Resistance

“…A lot of scientists devote their scientific works to this problem. We can see the parts of this theme in the works of F. Bencardino [1]; Green concrete production with ceramic wastes and laterite [2]; Strength and ductility characteristics of reinforcing steel bars milled from scrap metals [3]; Evaluation of the flexural behavior of composite beam with inverted-T steel girder and steel fiber reinforced ultra high performance concrete slab [4]; Predicting the post-cracking behavior of normal-and highstrength steel-fiber-reinforced concrete beams [5]; High-volume natural volcanic pozzolan and limestone powder as partial replacements for portland cement in self-compacting and sustainable concrete [6]; Improving degradation resistance of sisal fiber in concrete through fiber surface treatment [7]; Experimental investigations of size effect in reinforced concrete beams failing by shear [8]; Utilization of coal-and biomass-fired ash in the production of self-consolidating concrete [9]; Theoretical and experimental study on mechanical properties and flexural strength of fly ash-geopolymer concrete [10]; A review of waste products utilized as supplements to Portland cement in concrete [11]; Benefits of using blended waste coarse lightweight aggregates in structural lightweight aggregate concrete [12]; Evaluation of various treatment methods for enhancing the physical and morphological properties of coarse recycled concrete aggregate [13]; Time-dependent behaviour of steel tubular columns filled with recycled coarse aggregate concrete [14]; Investigation of using recycled powder from waste of clay bricks and cement solids in reactive powder concrete [15]; Eco-friendly concretes with reduced water and cement contents -Mix design principles and laboratory tests [16]; Recycling lead-based paint contaminated deconstructed masonry materials as aggregate for Portland cement concrete-…”

Estimation of Elastic Properties of Oil Palm Kernel Shell Concrete by Semianalytical Methods of Homogenisation

“…Until recently, few references were available in the literature concerning the MoE of OPKS concrete [6,[10][11][12][13][14][15][16][17][18], out of which few were concerned with its theoretical determination. In his theoretical approach for the determination of the MoE of OPKS concrete, Alengaram et al [6] used a modified form of the empirical equation of prediction, proposed by the code, CEB/FIP (MC2010).…”

“…Ahmmad et al [13] explained that the prediction equation reported by Alengaram underestimated the MoE of OPKSC and derived a new equation by comparing the MoE with the compressive strength. Aslam et al [16] compared the MoE values of OPKS estimated using Alengaram's equation with those estimated using other equations proposed in the literature to predict the MoE of LWACs and concluded that Alengaram's equation provides results that are closest to the experimental results. According to Mannan and Ganapathy [12], the MoE of OPKSC is strongly influenced by the intrinsic properties (such as stiffness) of the composite's two constitutive phases, i.e., the cement paste and the OPKS.…”
