TL;DR: In this paper, an artificial neural network (ANN) was used to predict the compressive strength of recycled aggregate concrete using 14 input parameters that included: the mass of water, cement, sand, natural coarse aggregate, recycled coarse aggregate used in the mix designs, water to cement ratio of concrete, fineness modulus of sand, water absorption of the aggregates, saturated surface-dried (SSD) density, maximum size, and impurity content of recycling coarse aggregate by volume, and the coefficient of different concrete specimen.
TL;DR: In this article, the development of lightweight aggregate concrete using fine aggregate that is manufactured from recycled waste polyethylene terephthalate (PET) bottles was presented, and the results of the first phase showed that the WPLA had a density of 1390kg/m3, a water absorption of 0% and a bulk density of 844 kg/m 3.
TL;DR: In this paper, an experimental study was carried out to investigate the recycling possibilities for fine aggregate of oyster shells (OS), which is an industrial waste, disposed of in open dumps at coastal oyster management areas.
TL;DR: In this article, the properties of concretes containing various waste E-glass particle contents were investigated in a study, where the size distribution of cylindrical glass particle was from 38 to 300 {mu}m and about 40% of Eglass particle was less than 150 µm, and the workability decreased as the glass content increased due to reduction of fineness modulus.
TL;DR: In this article, coal bottom ash is used as a sand replacement in concrete manufacturing, and compressive and splitting tensile strength of bottom ash concrete mixtures was almost comparable to that of control concrete mixture.
