What is the affect of age of concrete upon the water cement ratio and strength curve?
As concrete ages, its strength typically increases due to continued hydration of the cement particles, which can affect the water-cement ratio's impact on strength. Initially, a lower water-cement ratio leads to higher strength, but as concrete matures, the difference in strength between varying ratios diminishes. This means that while a low water-cement ratio is critical for achieving high early strength, the age of the concrete plays a significant role in enhancing overall durability and strength over time, regardless of the initial ratio. Thus, the strength curve generally shows a rising trend with age, independent of the initial water-cement ratio.

What is water to cement ratio?
Water/cement ratio law states that the strength of concrete is only dependent upon water/cement ratio provided the mix is workable.Strength of concrete primarily depends upon the strength of cement paste.Similarly, the strength of the paste increases with cement content and decreases with air and water content.
What is the lowest water cement ratio?
0.4
What is the mix for concrete and how does it affect the strength and durability of the final product?
The mix for concrete typically includes cement, sand, gravel, and water. The ratio of these ingredients affects the strength and durability of the final product. A higher ratio of cement to sand and gravel results in stronger concrete, while the proper amount of water is crucial for the mixture to bond and cure properly. Adjusting the mix can impact factors like compressive strength, durability, and resistance to cracking.

How the moisture content of the aggregates obtainable at site affect the water content ratio specified?
Obviously, if the aggregates are in a surface wet condition, meaning the moisture content is greater than the absorption, that surface water increases the water-to-cement ratio and affects strength and durability.

How do you assess the correct Water Cement ratio in cement mortar at any ratio?
Slump test
How cement get hard?
Cement hardens through a chemical process called hydration, where water reacts with the compounds in the cement to form crystals. This process creates a strong and durable bond between the cement particles, resulting in a solid and hardened structure. Factors such as water-to-cement ratio, temperature, and curing time can affect the strength and durability of the hardened cement.

What is water to cement?
Water cement ratio is defined as the indicator of strength is the ratio of water used compared to the amount of cement.Lower the W/C ratio, higher will be the strength.A minimum of W/C ratio 0.3 should be adopted.
