Sorel cement is the product of complex reactions of magnesium oxide, magnesium chloride and water with specific molar ratios. ... Cold crushing strength is one of the …
oxychloride (Sorel) cement was investigated. The results demonstrated that a concentration change of MgCl2 can strongly affect the properties of the Sorel cement. The amount of magnesium chloride was varied from 0.5 to 1.9 moles and the cold crushing strength (CCS) of each sample was measured after 2, 4, 10, and 20 days.

The average of three specimens gives the crushing strength of concrete. The strength requirements of concrete. Calculations of Compressive Strength. Size of the cube =15cmx15cmx15cm. Area of the specimen ... Compressive strength achieved by concrete at 7 days is about 65% and at 14 days is about 90% of the target strength.
The results showed that the samples produced with Sorel cement had high strength. Sample strengths produced with pumice used as aggregate are higher than those …
33N/mm2 – 53N/mm2 is Compressive strength of cement mortar after curing of 28 days. Compressive strength of cement is calculated in 1day, 3 days, 7 days and 28 days after curing period. As we know there is different types of cement ordinary Portland cement Portland pozzolana cement Portland slag cement and so many types.
The results of compressive strength of cement pastes cured in air at room temperature for 7 days noted that the mix containing 16.66wt.% of MgSO4 gives the best compressive strength.

According to section 19.2.1.3 of ACI 318-19 the specified compressive strength shall be based on the 28-day test results unless otherwise specified in the construction documents. 3- or 7-day test results are used to monitor early strength gain, especially when high early-strength concrete is used.
In this research, the effect of the addition of 2.5, 5, 7.5 and 10% magnesium sulphate to Sorel-20%wt SiC is studied. The cold crushing strength (CCS) of the samples measured after 10 days for different percentages of magnesium sulphate and showed that the addition of magnesium sulphate develops highest CCS.

It was developed after the invention of Portland cement in 1867 by S.T. Sorel and is popularly known as Sorel cement. ... The strength at 3 and 7 days for these mixes are significantly higher than that of one-day strength. This clearly indicates that the strength development of magnesium oxychloride cement is greatly influenced by the ...
The results reveal that MOC concrete has high compressive strength associated with high flexural strength and the ratio of compressive to flexural strength varies between 6 and 8.
