Feb 11, 2022 Similarly, the strength of the 20% replacement by SDBA showed a 5.7% increase in compressive strength at 28 days (5.84 0.241 N/mm 2 at 7 days and 6.12 0.125 N/mm 2 at 28 days). However, the strength improved marginally from 5.54 0.242 N/mm 2 on day 7 to 5.73 0.339 N/mm 2 on day 28 when cement was replaced with 30% of SDBA
With the average compressive strength of concrete at 28 days of curing (16N/mm2), for 1:3:3 mix ratio, we can deduce that 1:3:3 mix ratio can be adopt as a conventional mix design. 7 REFERENCES 1. Abdullahi M. (2013). Effect of aggregate types on

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

Standards for 7-day and 28-day strength test results. 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
Sample specimens for compression test were measured for density before crushing. The compressive strength test was carried out in accordance with BS EN 12390-7: 2009. Sample specimens were cured by immersion curing method and were tested at age of 7, 14, 28 and 56 days, respectively. 3
