C&D waste mainly consists of concrete, brick, glass, ceramic, steel, plastic and wood waste; the proportion of concrete and brick waste in C&D waste is more than 80%, and the other main components of C&D waste, such as glass and steel waste, have a specific recycling path [[36], [37], [38]].Therefore, improving the reclamation efficiency of concrete and brick …
Autoclaved aerated concrete (AAC) is the lightest masonry material available in today's building industry. It shows properties, such as high strength per unit weight, lesser density, lower shrinkage, higher thermal insulation, and fire resistance as compared to traditional concrete. Not only engineering properties of AAC make it popular in construction industry, but …

practical reutilization to recycle waste concrete requires further breaking and crushing of demolished concrete. Generally, two typical grades of crushed concrete aggregates
PURPOSE:To effectively reutilize concrete produced by pulling down a concrete structure as part of a new concrete structure by removing foreign matter from the concrete, mixing the concrete with mortar and solidifying the mixture. CONSTITUTION:Concrete 3 produced by pulling down the concrete structure 1 of a nuclear power plant or the like is thrown into a hole …
The STR are incorporated into concrete and prepared as STR concrete (STRC) using a coarse and fine aggregate shell production process. By optimizing the mixing method of STR slurry, we obtained the best mixing process, and studied the influence of STR dosage and water–binder ratio ( w / b ) on the compressive strength of STRC.
Ten mixtures were conducted. The lightweight concrete blocks powder and clay bricks powder were used to cast mortar samples in different levels (10%, 20%, and 30%) separately. Also, another group of cement replacing includes the combination of lightweight concrete blocks powder and clay bricks powder together with a 30% maximum of replacement.

Reutilization of scrap tyres in civil engineering applications, for example concrete production, can help prevent environmental issues as well as develop economically-friendly designs (Najim and Hall 2010). Recently potential research has been involved in replacing coarse and/or fine aggregate with waste rubber (from the scrap tyres).
Concrete incorporating self-ignition CG powder demonstrates high resistance to chloride ion penetration. Under water-binder ratios of 0.49 and 0.35, when the substitution level is less than 40 %, the chloride ion migration charge after …
Military units have always been first in line to claim used and excess items handed over to the Defense Logistics Agency as surplus stock. Now, as part of the agency's new 5-year strategic plan, DLA's reverse logisticians will focus more closely on increasing DOD reutilization frequency to help elevate troop readiness.

texture of pervious concrete also contributes to the skid resistance of roads [22]. Further-more, pervious concrete has the functional advantages of sound absorption and noise re-duction [23]. However, compared with traditional concrete pavement, its elastic modulus, compressive strength and flexural strength ar e generally lower [24 27].
Concrete mixture B5 thus seems to have a less porous structure than reference concrete B0 for two reasons: the w/c ratio reduction induced by the presence of up to 5% GFRPW (w/c of 0.39 for B5, against 0.40 for reference mixture B0) and a fall in the number of pores, which are incidentally smaller and have poorer communication. This shows that ...

The construction and demolition (C&D) of building structures and infrastructures has generated large amount of wastes in Singapore. The disposal of C&D waste poses a major environmental problem due to land scarcity. This triggers a need to look into the possible use of C&D waste for more beneficial applications. On the other hand, lack of […]
Concrete recycling is a well-established industry in many countries, albeit limited to the simple crushing of waste concrete and using only the coarse fraction as aggregate. The fine fractions generally remain undervalued, meaning an obstacle for full re-utilization and commercialisation of waste concrete. Low recovery rates also affect the ...
