The compressive strength of hardened cement is most important of all the properties. In this test 555 gm of standard sand, 185 gms of cement (1:3;ratio of cement to sand) is taken in a tray and mix them with a trowel for 1 minute and water is added of quantity ()% of combined we...
There is no clear relation between consistency and compressive strength. Inverse linear relations exist between less than 63 microns size fraction and strength. To account for the differences in compressive strength at different ages and using different cement brands, it is very important to identify ...
The difference between the 7th and 28th day compressive strengths is small. This is because the pozzolana-ALS cements were cured at 54 ± 2 °C. This is an accelerated hydration (Lea, 1973). The test samples would therefore be ideal for the making pozzolana-lime cement. Sample 2, which ...
C109/C109M Test Method for Compressive Strength of 1.1.7 Type III—For use when high early strength is desired. Hydraulic Cement Mortars (Using 2-in. or [50-mm] Cube 1.1.8 Type IIIA—Air-entraining cement for the same use as Specimens) Type III, where air-entrainment is desired. ...
The method is applicable to Portland cement, ordinary portland cement, slag cement, volcanic ash cement and fly ash water Test on flexural strength and compressive strength of mud. Any other type of cement designated for this method shall be tested after determining the water cement ratio Applicabl...
Type III is high early strength cement. It is produced by finer grinding of a clinker with a higher percentage of C3A and C3S. The gypsum level is increased slightly. Concrete using this cement has a 3-day compressive strength approximately equal to the 7-day compressive strength for Types...

However, after 90 days of sealed curing, the 0.05% dosage of DCNF with 75% fine contents showed an increase in compressive strengths by 15%. Cement paste samples containing 0.1% DCNF did not show any notable increase in the compressive strength of the cement paste for the tested curing ...
Integrating artificial intelligence and green concrete in the construction industry is a challenge that can help to move towards sustainable construction. Therefore, this research aims to predict the compressive strength of green concrete that includes a
