A crushing plant is a one-stop crushing installation, which can be used for rock crushing, garbage crushing, building materials crushing, and other similar operations. Crushing plants may be either fixed or mobile. Useful aggregates from raw materials like stones, rocks, and minerals as their main function. Draw attention to the value of these ...
1. Introduction. Concrete waste, a critical component of several billion tons of construction and demolition waste, has attracted significant attention for its recycling and reuse (Akhtar and Sarmah, 2018; Kumar et al., 2023; Leemann et al., 2023).In particular, using recycled coarse aggregates (RCA) produced from scrap concrete (Munir et al., …

Noruzman, Muhammad [81] tested the workability and setting time of green concrete using water from three distinct sources: an industrial facility, a palm oil factory, and a residential sewage treatment plant. Testing revealed that using wastewater from the heavy metal industry was the best choice for the green concrete samples.
Integrating wastewater into green concrete depends on its quality and treatment. Industrial effluents with heavy metals and organic compounds require careful …
This research investigates the effect of pre-soaking treatment on plant-based aggregate using a wet grout binder to formulate a high-strength lightweight concrete (HSLWC). Surface modification utilising a novel grout soaking technique with various water-to-cement (w/c) ratios has indicated a new method of approach for the recent …
A concrete mixing plant that is based on sea container dimensions is equipped with factory insulated and electrified structures. These modular structures are not only used as frame structures but at the same time serve for other functions and provide storage space. The supporting structures consist of empty containers on the ground level ...
Water has prime importance in the production of cement-based materials (CBMs), such as paste, mortar, and concrete [ 1 ]. Concrete is produced by mixing binding materials (Portland cement or asphalt) and inert materials (coarse and fine aggregates) with water [ 2 ]. Globally, concrete requires around 1 trillion gallons of water yearly [ 3 ].
