“…The main hydration reactions between water and the following systems were thought to occur: CaO; MGO; And K2O. The remaining compounds, in general, are not changed during material processing [39]. Since the particle size of ceramic tile waste is smaller than natural, the compressive strength for each percentage of the three wastes used instead of sand and cement, The results obtained for porosity and water absorption were compared with control concrete.…”

Material recycling is the sustainable use of a substance, sustainable production, additive production, powder reuse, knowledge management, reuse of water, etc. Is the process of picking up old items and finding new ones? ... Sometimes items can be reused by others. Clothes can be donated frequently and given a second life. Recycling is better than recycling because it saves energy coming from disposing and recycling materials.This significantly reduces waste and pollution because it reduces the need for raw materials and saves both forest and water supply. When we do not recycle, reuse and reduce, we are destroying natural habitats. As it is, our planet cannot cope with the current rate of destruction. If we fail to reuse what we already have, we end up in a sticky situation of running out of resources. By reducing our waste, we are conserving our resources. Resources such as aluminum, petroleum and wood are all used to make new products such as cans, plastic bags and paper packaging. Less energy is used to recycle materials as opposed to creating new ones.

“…Recently, the study of using waste materials to enhance the carbonation resistance in mortars has attracted attention in order to improve the properties of mortars [ 52 , 53 , 54 , 55 , 56 , 57 ]. Recent studies have analysed the acceleration of carbonation of two types of lime mortars (standard sand and extra ceramic dust) [ 58 ]; the mortar with extra ceramic dust showed advanced calcite precipitation and early improvement in various properties.…”

Effect of the Addition of Agribusiness and Industrial Wastes as a Partial Substitution of Portland Cement for the Carbonation of Mortars

The present research work shows the effect on the carbonation of Portland cement-based mortars (PC) with the addition of green materials, specifically residues from two groups: agricultural and industrial wastes, and minerals and fibres. These materials have the purpose of helping with the waste disposal, recycling, and improving the durability of concrete structures. The specimens used for the research were elaborated with CPC 30R RS, according to the Mexican standard NMX-C-414, which is equivalent to the international ASTM C150. The aggregates were taken from the rivers Lerma and Huajumbaro, in the State of Michoacan, Mexico, and the water/cement relation was 1:1 in weight. The carbonation analyses were performed with cylinder specimens in an accelerated carbonation test chamber with conditions of 65 +/− 5% of humidity and 25 +/− 2 °C temperature. The results showed that depending on the PC substitutions, the carbonation front advance of the specimens can increase or decrease. It is highlighted that the charcoal ashes, blast-furnace slags, and natural perlite helped to reduce the carbonation advance compared to the control samples, consequently, they contributed to the durability of concrete structures. Conversely, the sugarcane bagasse ash, brick manufacturing ash, bottom ash, coal, expanded perlite, metakaolin, and opuntia ficus-indica dehydrated fibres additions increased the velocity of carbonation front, helping with the sequestration of greenhouse gases, such as CO2, and reducing environmental pollution.
