“…This trend in the strength gain is similar to results for the compressive strength and tensile strengths of concrete, as mixing SF with concrete influenced concrete and enhanced its strength the most. Results from Mydin [19] show that mixing SF leads to an increase in the flexural strength of concrete as shown in Fig. 10.…”

-This research aims to investigate the effect of introducing different mineral admixtures on the mechanical properties of concrete. The research is focused on optimizing the properties of fresh and hardened concrete, looking in particular at how factors such as slump, unit weight, air entrancement, compressive strength, tensile strength, flexural strength and modulus of elasticity are affected by different mineral admixtures in a concrete mix. Different mineral admixtures are used, namely silica fume, limestone and ultra-fine gypsum, and for the tests each mineral admixture replaced 25 % of the cement. The paper also compares the performance of the fresh and hardened properties of concrete.

Integrating artificial intelligence and green concrete in the construction industry is a challenge that can help to move towards sustainable construction. Therefore, this research aims to predict the compressive strength of green concrete that includes a ratio of cement kiln dust (CKD) and fly ash (FA), then recommend the optimum sustainable mixture design. The artificial neural network (ANN) and multiple linear regression techniques are used to build prediction models and statistics using MATLAB and IBM SPSS software. The input parameters are based on 156 data points of concrete components and compressive strengths that are collected from the literature. The developed models have been trained, validated, and tested for each technique. TOPSIS method is used to assign the optimum mixture design according to three sustainable criteria: compressive strength, carbon dioxide (CO2) emission, and cost. The results of ANN models showed a better prediction of the compressive strength with regression (R) equal to 0.928 and 0.986. The optimum mixture includes CKD 10–20% and FA 0–30%. Predicting the compressive strength of green concrete is a non-destructive approach that has sustainable returns including preservation of natural resources, reduction of greenhouse gas emissions, cost, time, and waste to landfill as well as saving energy.

“…In the United Kingdom, the estimates for waste concrete are 30million tonnes/year, which comes to about 500kg/person/year [1], with construction waste becoming a major concern to the community. In Malaysia, as a developing country, the waste product from the construction industry is not being taken seriously because almost all construction in Malaysia is based on building and not demolishing buildings [2]. The use of concrete in construction is common and almost all types of development use concrete to form a structure.…”

This paper presents an experimental study of the influences of different percentage waste concrete ash used as cement replacement materials to form a new concrete. The experimental process will be evaluated based on mechanical performance and durability of the concrete. To improve the quality of cement replacement concrete, another concrete admixture was added to work with the waste concrete ash. The mix proportioning of the waste concrete ash used is between 5% and 40% of the replacement cement materials, and for concrete admixture is fixed in optimum amounts. Every specimen is cured in water until it reaches the right age to be tested, and in this experiment, the specimens will be tested at the age of 7, 14, 28, 90 and 180 days. Based on this study, it is revealed that increasing a percentage of waste concrete ash will reduce the quality of concrete. However, the addition of concrete admixture will restore the strength of the concrete. Furthermore, it shows that an increase of Waste Concrete Ash in percentage of cement replacement will cause a loosening between the binders and aggregate, thereby lowering the compressive strength.
