“…Due to the limited quantity of siliceous fly ash and granulated blast furnace slag in the decarbonization of the energy and metallurgy sectors, other alternative materials are being looked for [ 1 , 9 ]. The best solutions include raw materials with pozzolanic properties that do not require additional thermal or chemical treatment, such as zeolite, spongilite, diatomite, pumice and trass [ 16 , 17 , 18 , 19 , 20 , 21 ]. Some of these natural pozzolans have been used to improve the performance of non-hydraulic binders since ancient times.…”

“…The cellular structure of pumice is the result of the formation of bubbles or air voids when gases contained in lava flowing from volcanoes are trapped during cooling [ 23 , 24 ]. Studies in which cement was partially replaced in pastes were carried out by, among others, the authors of the publications [ 19 , 21 , 23 ]. Kocak et al [ 19 ] tested cement mortars modified with pumice and diatomite, and they replaced 5% or 10% of the cement with the addition of one of these or 10 or 20% with their combination.…”

In this article, the physico-mechanical properties and hydration processes of cement pastes containing three additives are introduced. Cement was replaced with pumice, trass, waste chalcedonite powder at 30% by mass and a combination of pumice or trass and waste chalcedonite powder in the amounts of 15% each. The main aim of this research was to assess the properties of two- or three-component binders to save cement in these binders. Rheological properties such as consistency, yield stress, viscosity and thixotropy were determined, in addition to porosity, 7-day and 28-day flexural and compressive strength and bulk density. Additionally, the heat evolution and degree of hydration of the tested pastes were compared. The use of all additives resulted in a reduction in the consistency of the tested pastes. The highest compressive strength measured after 28 days was observed for the cement paste with a 30% content of waste chalcedonite powder, which is related to it having the best pozzolanic activity of the materials used. The results of this research have confirmed that pumice, trass and waste chalcedonite powder can be used as components of blended Portland cements.

This study implements a set of machine learning algorithms to building material science, which predict the compressive strength of zeolite and diatomite substituting concrete mixes in sodium chloride solution. Particularly, Random Forest, Support Vector Machine, Extreme Gradient Boosting, Light Gradient Boosting, and Categorical Boosting algorithms are exploited and their optimal parameters are tuned. In the training and testing of these models, 28 day, 56 day, and 90 day compressive strength observations of 63 samples of 7 different concrete mixtures substituting Portland cement, zeolite, diatomite, zeolite + diatomite were used. Consequently, compressive strength experimentation results and machine learning predictions were compared through statistical methods such as RMSE, MAPE, and R2. Results denote that the prediction performance of machine learning is improving with tuned models. Particularly, RMSE, MAPE, R2 scores of Categorical Boosting are, respectively, 1.15, 1.45%, and 98.03% after parameter tuning design. The results denote that presented machine learning model can provide an advantage in the cost and duration of the compressive strength experiments.
