Reusing ceramic wastes in concrete
TL;DR: In this article, the feasibility of using calcined-clay wastes in concrete was examined and it was shown that concrete with 20% cement replacement outperformed the control concrete mixtures concerning compressive strength, capillary water absorption, oxygen permeability and chloride diffusion.
Journal ArticleDOI
Using ceramic sanitary ware waste as concrete aggregate
TL;DR: In this article, the authors present the results of examination of concrete with alumina cement and ceramic sanitary ware wastes as aggregate in 1000°C temperature, and show that these specimens after heating continued to display high compressive and tensile strength.
Journal ArticleDOI
The utilization of eco-friendly recycled powder from concrete and brick waste in new concrete: A critical review
TL;DR: In this article, the median diameter and replacement ratio of Recycled Powder (RP) concrete should be below 30μm and 30%, respectively, to improve the durability of concrete when the RP fineness is superior to the cement fineness.
Journal ArticleDOI
Utilization of recycled brick powder as alternative filler in asphalt mixture
TL;DR: In this article, the use of recycled brick powder as replacement of mineral filler in asphalt mixture was investigated and a comparative study was carried out on the performance of two mixtures using recycled bricks powder and limestone filler.

A study of the mechanical properties of ground ceramic powder concrete incorporating nano-SiO2 particles
Ali Heidari,Davoud Tavakoli +1 more
TL;DR: In this article, the use of waste ground ceramic as a pozzolan in concrete was investigated and the results showed that adding ground ceramic up to 20% does not have a significantly negative effect on the compressive strength of concrete and that using any amount of ground ceramic in concrete reduces its water absorption capacity.

Metakaolin and calcined clays as pozzolans for concrete: a review
B.B. Sabir,S. Wild,J. Bai +2 more
TL;DR: The use of metakaolin (MK) as a pozzolanic material for mortar and concrete has received considerable attention in recent years as mentioned in this paper, which is part of the widely spread attention directed towards the utilisation of wastes and industrial by-products in order to minimise Portland cement consumption, the manufacture of which being environmentally damaging.

Pozzolanic reactions of six principal clay minerals: Activation, reactivity assessments and technological effects
TL;DR: In this paper, the compressive strength of mortars based on the raw clays is affected by structure of clays, and a close correlation exists between the clays' pozzolanic activity and the particle size distribution of dehydroxylated clays.

Mineral admixtures in mortars Effect of inert materials on short-term hydration
TL;DR: In this article, a phenomenological approach, based on semi-adiabatic calorimetry, is only associated with first-order phenomena, and the study excludes the complex physicochemical details involved in the chemistry of cement.
Journal ArticleDOI
Influence of pozzolan from various by-product materials on mechanical properties of high-strength concrete
TL;DR: In this paper, the effects of pozzolan made from various byproduct materials on mechanical properties of high-strength concrete were investigated and the results suggest that concretes containing FA, FB, RHBA, and POFA can be used as pozzolic materials in making high strength concrete with 28-day compressive strengths higher than 80 MPa.

Study of the pozzolanicity of some bricks and clays
Giulia Baronio,Luigia Binda +1 more
TL;DR: In this paper, a systematic research on the pozzolanicity of different bricks and clays was carried out, based on chemical, mineralogical-petrographical analyses and pozzolicity tests, applied to measure the capacity of crushed bricks in fixing calcium hydrate.
