Technical and environmental characterisation of recycled aggregate for reuse in bricks [PDF]

, 2017
Waste mud coming from an aggregate washing plant was formerly used as filling material for a pond, aimed at the recovery of an abandoned quarry. Once completed the filling capacity of the pond, the need for identifying a possible reuse of mud produced by

Crack healing in cementitious materials including test methods [PDF]

, 2020
If concrete is crack free, deleterious substances can be avoided entering the body of the material, that may corrode the rebar or encourage freeze/thaw damage. This paper examines a self healing system of cementitious materials.

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

Advanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Autogenous shrinkage, speciality of high performance concretes [PDF]

, 2015
Autogenous shrinkage is a consequence of self dessication in pores of hardened cement paste and is, at high performance concrete significantly greater than that of the ordinary concretes, mainly due to low water to cement ratio.

Mechanical Properties of Light Weight Concrete using Lightweight Expanded Clay Aggregate

International Journal for Research in Applied Science and Engineering Technology, 2022
Abstract: This research investigates the impact of partially substituting coarse aggregate with light weight coarse material (LECA). In numerous aspects, LECA mirrors the properties of coarse aggregate. Because self-weight accounts for a major amount of the total load applied to the structure, LECA is utilized in concrete to lower the need for coarse ...
