To reduce CO2 emissions from the building industry, one option is to replace cement in specific applications with alternative binders. The Carbstone technology based on reaction of calcium- and magnesium-containing minerals form carbonate Mixes carbon steel slag stainless-steel slag, tailored particle size distributions, were compacted a vibro-press subsequently carbonated an autoclave produce ...

Due to the current concern with environmental impacts produced by construction industry, many studies have been conducted capitalize on advantages of waste develop sustainable materials. The study reports an innovative, non-conventional cement-based composite material containing 10 wt.% vine shoot waste, representing a step forward toward use this lignocellulosic waste. investigations were carr...

This paper investigates the synergistic interaction between carbonation and microcracks in hardened cement pastes. Ordinary Portland pastes with three different water/cement ratios of 0.4, 0.5 0.6, hydrated for 28 days crack apertures ranging from 10 to 150 ?m were subjected accelerated a climate chamber that controls targeted relative humidity (65 75%), CO2 concentration (0.3 vol.% 1 vol.%) te...

this paper aims at investigating the influence of partial replacement of portland cement with ultrafine fillers compared to limestone powder on the durability and mechanical characteristics of concrete. for this purpose, ultrafine calcium carbonate materials with different specific surface areas of 9.7 and 15.1 m2/g and limestone powder (0.72 m2/g) were used. the results indicate that the ultra...

For most fires, forensic investigation takes place well after building materials have cooled and knowledge of the structural damage due to heat exposure can reveal the temperature reached during an incident. Recently, there have been significant changes in the types and hence characteristics of cementitious materials used in the United Arab Emirates. Few studies focus on the application of ther...

The information obtained using the satellite technologies of remote sensing provides new massive knowledge about open pit mining operations at deposits carbonate rocks for manufacture cement in 26 regions Russia. number and haulage machines operating each individual mine within whole industry sector is determined. was used analytical estimation capacity overall potential production this sector....

Microbially Induced Calcium Carbonate Precipitation (MICP) is a natural biocementation that takes place in corals, stromatolites and beach rocks. In recent years, researchers have explored the emulation of this process as sustainable alternative engineered cement. Although undoubtedly sustainable, its variant deviates substantially from process. paper, we investigate environmental economic perf...
