explore this possibility. In addition, since the abrasion of concrete is a mechanical degradation process, surface hardness and unconfined compressive strength tests were also used to estimate abrasion resistance. 2. EXPERIMENTAL PROCEDURES 2.1 Abrasion resistance Abrasion resistance of concrete was assessed using an
6. Abrasion and Erosion Resistant Admixtures. Admixtures that add durability integrally to concrete can deliver long-lasting, abrasion and erosion-resistant concrete while also lowering the embodied carbon emissions of an industrial floor project. Hard-Cem is one example of this. It is a concrete admixture for abrasion and erosion …

In order to obtain concrete mixes resistant to abrasion, appropriate concrete compressive strength, number and type of air pores, water-cement index, and type and properties of the aggregate used ...
A. Actions needed to resist abrasion depend on the type of structure and abrasive action to be resisted. For concrete floors, the mortar fraction needs to be resistant to abrasion (ACI 302.1R). Abrasion resistance of concrete is measured by different standard test procedures: ASTM C418, ASTM C779, ASTM C944, and ASTM C1138.
abrasion resistance of concrete by sand blasting technique. ASTM C 944 test method measures the abrasion resistance of concrete by rotating-cutter machine. ASTM C 779 method evaluates the abrasion resistance of horizontal concrete surface by either revolving disc machine or by ball bearing machine and ASTM C 1138 method
abrasion resistance of concrete floors [37]. Horszczaruk reported that steel fiber with an aspect ratio above 50 and polyurethane fiber increased the abrasion resistance of high-performance concrete (HPC) [38]. However, Nanni, Atis et al., and Sonebi and Khayat found that fibers had no effect on the abrasion resistance of concrete [39–41].
aggregate toughness/abrasion resistance and durability/soundness that are related to the performance of asphalt concrete pavements. Toughness/ Abrasion Resistance Aggregates must be tough and abrasion resistant to prevent crushing, degradation, and disintegration when stockpiled, fed through an asphalt plant, placed with a paver, …

Abrasion resistance of concrete pavement is a surface property that is mainly dependent on the quality of the surface layer characteristics. A common assumption is that a concrete surface is abrasion-resistant when acceptable compressive strength is obtained. This indirect approach is for the most part effective and reasonable, but not always ...

The phenomenon of hydraulic structure concrete abrasion, caused by the water-carried sediment abrasion process, is analyzed in this paper. There was detailed investigation of laboratory procedure adequacy for definition of concrete abrasion level in standard ASTM C1138 hydraulic structures. Assessment was based on comparison of …
High abrasion resistant aggregate produced a concrete with high abrasion resistance.Three-month compressive strengths of concretes made with basalt, limestone and sandstone were found to be ...
Abrasion resistance resists mechanical wear. Abrasion-resistant materials are useful for both moving and fixed parts in settings where wearing is an issue. Abrasion resistance has close proximity to the compressive strength of concrete. Strong concrete is more abrasion-resistant than weak concrete. The abrasion resistance of materials …

How is the abrasion resistance of concrete determined? A. Resistance to abrasion can be determined by ASTM C418, ASTM C779, and ASTM C944. References: SP-1(02); ACI 201.2R-16; ASTM C33; ASTM C418; ASTM C779; ASTM C944. Topics in Concrete: Durability; Pavement; Slab; Testing of Concrete.
This investigation evaluates the resistance to abrasion of concrete proportioned to have four levels of fine aggregate replacement (5, 10, 15, and 20 percent) with silica fume, a byproduct of the silicon metal and ferrosilicon industry. Control mixes containing no silica fume are also used for comparison purposes. Three cement factors, …
