The demand for concrete has increased manifolds due to rapid urbanization and
development across the globe. Natural fine aggregates (NFA) and natural coarse …

In this work, the local low-cost materials from Nigeria were companied together to produce a
lead-free concrete that can be used in shielding the ionizing γ-rays. This work investigated …

The application of recycled coarse aggregate (RA) to produce recycled aggregate concrete
(RAC) requires the investigation of its mechanical properties. From literature review, it is …

The future construction industry will demand for sustainable concrete, either by recycling or
direct incorporation of industrial by-products for effective solution of ecological concerns …

Many researchers have carried out works on use of various agricultural and industrial by-
products to enrich the performance and strength characteristics of concrete. The study here …

The fundamental reason to the unsatisfied performance of recycled aggregate concrete
(RCA) is the existence of attached mortar in recycled concrete aggregate. A new physical …

The fundamental reason for the poor performance of recycled aggregate (RA) and recycled
aggregate concrete (RAC) is the attached mortar, which severely restricts the application of …

To explore the basic mechanical properties and size effects of recycled aggregate concrete
(RAC) with different substitution ratios of coarse recycled concrete aggregates (CRCAs) to …

In this study, the use of recycled fine aggregates and waste powders in mortar was
discussed, in which the pozzolanic reaction and the effect on strength properties of the …

Solutions are needed to solve the problem of a large amount of construction solid waste and
a shortage of natural aggregate (coarse and fine aggregates). In this paper, simple-crushed …
