Synergistic effects of supplementary cementitious materials and compressive strength prediction of concrete using machine learning algorithms with SHAP and PDP analyses

Case Studies in Construction Materials
In order to reduce the CO2 associated with cement production, this study explored the potential of rice husk ash (RHA) and fly ash (FA) as supplementary cementitios materials for partially replacing cement in concrete production.

Predicting Concrete Compressive Strength and Modulus of Rupture Using Different NDT Techniques

Advances in Materials Science and Engineering, 2014
Quality tests applied to hydraulic concrete such as compressive, tension, and bending strength are used to guarantee proper characteristics of materials. All these assessments are performed by destructive tests (DTs).

A Comparative Analysis of the Rebound Hammer and Pullout as Non-Destructive Method in Testing Concrete

European Journal of Engineering Research and Science, 2020
A comparative analysis between Rebound Hammer and Pullout method in testing concrete was conducted in this study. Experimental analysis were carried out to compare the correctness between the two testing method in estimating the strength of concrete. Different cube (cubes of 175 x 175 x 175) samples were prepared using two mix designs of 1:2:4 and 1:3 ...
