Study of Waste Plastic Mix Concrete with Plasticizer
TL;DR: It was found that the reduction in workability and compressive strength, due to partially replacement of sand by waste plastic, is minimal and can be enhanced by addition of superplasticizer.
Effect of Fly Ash on Mortar Mixes with Quarry Dust as Fine Aggregate
TL;DR: In this paper, the compressive strength and transverse strength of 1":"3 mortar mixes in which natural sand was replaced with 20%, 50%, and 100% quarry dust by weight which were further modified by partially replacing cement with four percentages (15, 20, 25, and 30%) of low calcium fly ash.
Prediction of rapid chloride permeability of self-compacting concrete using Multivariate Adaptive Regression Spline and Minimax Probability Machine Regression
TL;DR: In this paper, the authors presented new models to predict chloride penetration into self-compacting concrete (SCC) using the rapid chloride penetration test (RCPT), which mainly focuses on the effect of supplementary cementitious material (i.e., fly ash and silica fume) and elevated temperature curing of SCC on results of the RCPT.

Abstract: This paper statistically investigates the influence of parameter, namely curing temperature, molarity, NaOH/Na2SiO3, and activator‐to‐fly ash ratio on the compressive strength of low calcium fly ash‐based geopolymer concrete. This paper also investigates the effect of delay time prior to curing on the compressive strength of geopolymer concrete. The results of the experimental investigation show that these parameters notably influence the development of the mechanical strength of the final product. The statistical investigation shows that the early compressive strength is significantly affected by the synergistic effect of a linear term of curing temperature, molarity, and activator‐to‐fly ash ratio while NaOH/Na2SiO3 ratio was found to be not so statistically significant. The numerical algorithm formulated using regression analyses were simultaneously optimized by utilizing response optimizer method. A constitutive model which represents a relationship between the compressive strength and splitting tensile strength is also proposed.
