The roles of biochar as green admixture for sediment-based construction products

Cement & Concrete Composites, 2019
Routine navigational dredging generates huge quantities of marine sediment, posing significant environmental and economic burden. This research intended to explore the efficacy of wood waste biochar as a green admixture and assess the influence of ...

A Review of Microwave Absorption and Reflection by Cement‐Based Materials, With Emphasis on Electromagnetic Interference Shielding and Admixture Effects

Advanced Functional Materials
Cement‐based materials can be modified for microwave reflection/absorption. Admixtures (particles or short fibers) include conductive, dielectric, and magnetic ones, used solely or in combination. Synergism occurs with conductive and magnetic admixtures,

Application of shrinkage reducing admixture in concrete: A review

Construction and Building Materials, 2019
The utilization of shrinkage reducing admixture (SRA) in concrete has been received considerable attention in recent years. SRA is being used very commonly to reduce the shrinkage of concrete, and has presented considerable effect on the properties of ...

Pervious concrete for desired porosity: Influence of w/c ratio and a rheology-modifying admixture

, 2020
A simple design method is proposed to obtain the desired porosity by controlling density and compaction efforts. Then, the w/c ratio and chemical admixture were varied to obtain the desired porosity and to evaluate their influence on the permeability and

Effects of water to cement ratio, recycled fine aggregate and air entraining/plasticizer admixture on masonry mortar properties

, 2020
The main aim of this study has been to determine the influence of total water to cement ratio, recycled fine aggregate from construction and demolition waste, and air entraining/plasticizer admixture on the properties of masonry mortar. Two mortar series

Effect of side chain length change of polycarboxylate-ether based high range water reducing admixture on properties of self-compacting concrete

Construction and Building Materials, 2020
In this study, the effect of side chain length, molecular weights changes and adsorption amount of polycarboxylate ether-based high range water reducing admixtures having constant main chain length, free non-ionic amount and anionic/non-ionic ratio on ...

Effects of waterproofing admixture on the compressive strength and permeability of recycled aggregate concrete

, 2020
The recycling and reuse of demolished concrete aims to preserve the environment by reducing the waste disposal areas. Moreover, the replacement of virgin aggregates with aggregates obtained by crushing concrete waste can decrease the new quarries ...

Admixture in Latin America

Current Opinion in Genetics & Development, 2016
Latin Americans arguably represent the largest recently admixed populations in the world. This reflects a history of massive settlement by immigrants (mostly Europeans and Africans) and their variable admixture with Natives, starting in 1492. This process resulted in the population of Latin America showing an extensive genetic and phenotypic diversity.
