Sorel-SiC composite due to the great abrading behavior, has been used in abrasive tools specially in grinding stone. One of the most important factors in abrading behavior of these composites is the great cold crushing strength (CCS). In this research, the effect of the addition of 2.5, 5, 7.5 and 10% magnesium sulphate to Sorel-20%wt SiC is ...
Recently, more studies have focused on the production of economic LWAs, using the cold-bonding process to produce sustainable lightweight aggregates by various industrial by-products (Tang et al., 2020b; Tang and Brouwers, 2017, 2018).Normally, ordinary Portland cement (OPC) is a necessary binder during the pelletizing process to provide adequate …
Artificial aggregates, such as fly ash lightweight aggregates, can be used as eco-friendly alternatives to natural aggregates. This work aims to investigate the effect of curing time on the hydration and material properties (voids, shrinkage, crushing strength and pH) of cold-bonded high-calcium fly ash–Portland cement lightweight aggregate. Fly ash was used as a …

Modulus of rupture can be performed at elevated temperatures to determine its relative strength in service using the Hot Modulus of Rupture (HMOR) test. ASTM C-133; Cold Crushing Strength Related to Refractory: Cold crushing strength measures the compressive strength of a refractory. The test is performed at room temperature after drying or firing.
The densification parameters for sub-bituminous coal briquette were optimized in this study to obtain 12 maximum drop to fracture (DF), water resistance index (WRI), and cold crushing strength (CCS).
Flexural strength tests of all mortar batches, performed on cuboid samples and boards of the thickness of 1 cm, demonstrated a similar improvement in strength. The lowest value of compressive strength was recorded for the reference batch at 46.6 MPa, whereas the highest value was recorded for the second batch containing sodium silicate, at 49.8 ...
concrete crushing strength - . The simple Cold Crushing Strength (CCS) test (ISO 8895-86) is used widely even though refractories rarely fail in service by crushing at room temperature. This test, however, is an indirect quality control check—samples failing this may, e.g., have been inadequately fired or have poor abrasion resistance.
Following Part 1 of this publication series which dealt with the procedure and the determination of precision of Cold Crushing Strength (CCS) data on several refractory brick grades, part 2 …
