A: Concrete grinding is a process used to level, smooth, and refine the surface of concrete floors and other concrete structures. It involves using specialized equipment equipped with diamond grinding discs to remove unevenness, imperfections, and surface coatings from the concrete, resulting in a smoother and more even surface. Q: 2.

The Compacting Recycler is crafted from 7 Pistons, a Recycler, and an Advanced Machine Block. As with the normal Recycler, any items inserted has a chance to become Scrap; else, it will disappear. Any Metal Items inserted has a chance to become Scrap Metal, and if 9 Scrap is inserted, will compress into a Scrap Box: if Scrap is …
1. Introduction. Self-compacting concrete (SCC) is a kind of high-performance green concrete. Its main characteristics are that it can flow through reinforcement gaps and fill the corners of molds and voids in rock blocks simply under its own weight during placement, reducing the process of vibration and enhancing the …
The use of recycled coarse aggregates (RA) in concrete is a sustainable alternative to non-renewable natural aggregate (NA) to fabricate concrete products using in concrete structures. However, the adhered mortar on the surface of RA would considerably impact the qualities of concrete products. As a practical treatment procedure, …
This agrees with the results published by Domone [26] where the mean coarse aggregates content was 31.2% in volume and the mean powder content is 500 kg/m 3.The results published by Jin [25] agree with these and follow a similar trend. Finally, the recommendations of the European Guidelines for self-compacting concrete [12] refer a …
The authors applied multiple regression analysis so that the effects of fiber and cement content on the viscosity of the concrete could be quantified and consequently, the following equations were obtained: (1) V f = 13.02–0.00198 S + 0.8017 P (R 2 = 0.9966) (2) S f = 608.5 + 0.332 S-14.9833 P (R 2 = 0.9882) Where V f is the V funnel flow ...

High-performance Self-compacting concrete (HP-SCC) is an SCC with high compressive strength (CS) [7]. Generally, such an HP-SCC is obtained with high cement ranges and a low water/cement (w/c) ratio, which can be improved by using inactive or active supplementary materials to the mix [8]. To ensure that materials will last a long …
Santos et al. (2019b) developed a concrete by incorporating coarse and fine RCA at several replacement rates (25/25, 50/50, 100/0 and 0/100) and FA, keeping the effective w/c ratio constant. Their results showed that an SCC could be obtained with precise and careful dosing by using an RCA with a high content of fines.
