Blended cements based on the partial replacement of Portland cement clinker (PC) by wastes have been the subject of many investigations in recent years. The use of the replacement materials offer cost reduction, energy savings, arguably superior products, and fewer hazards in the environment. These materials participate in the hydraulic reactions, contributing significantly to the composition a...

The pulp and paper industry generates a significant volume of solid waste during its operations. In order to mitigate the environmental impact caused by this industry, one residues was applied in eco-friendly composites. Therefore, research aims use green liquor dregs as partial replacement for lime coating mortars. Hydrated replaced percentages 10%, 15%, 20%, 30%, manufactured mortar specimens...

This article studies the influence of biopolymeric viscosity-modifying admixtures with water-retentive function on physico-mechanical properties natural hydraulic lime-based mortars and their adherence to traditional fired-clay brick substrate. The use increases water/binder ratio, which in turn leads a decrease strength mortars. improves adhesive between mortar pre-wetter by increasing binder ...

In this work, air lime mortars were bioformulated with two innovative bioproducts, one resulting from iron supplemented Escherichia coli cultures and a second exploiting microbial mixed grown crude glycerol as substrate. The bioproducts lyophilized and, for the mortar formulation, suspended in water used mixing liquid. Workability of was evaluated by flow table consistency 90-days-old samples t...

Flexibility of Lime Mortar resulting from its good permeability feature through relatively large interconnected pore structure makes it popular as an old sustainable building material. This characteristic enhances capability to suppress masonry deformation. However, mechanical strength is weak. To address this shortcoming, cement added form a stronger composite. study, therefore, evaluates the ...

In order to mitigate climate change, reductions of energy consumption are required on heating systems for residential and non-residential buildings. Despite radiant floor being widely used due their high thermal efficiency comfort, further improvements necessary reduce the carbon footprint mortars used. This paper studies use lime mud, a by-product industry, as partial replacement cement enviro...

In order to obtain a reasonable plan for synchronous grouting of the shield in anhydrous sandy cobble stratum, based on basic physical and mechanical characteristics stratum local construction conditions, material was selected, influence various factors mortar performance analyzed orthogonal experiments, multi-objective optimization carried out BP neural network genetic algorithm. The results s...
