On increasing the water-cement ratio, the strength of cement paste generally_______?

  1. On increasing the water-cement ratio, the strength of cement paste generally decreases. This is because the water-cement ratio refers to the proportion of water to cement used in a concrete or cement mixture. Cement requires a certain amount of water to hydrate and form strong chemical bonds. If you add more water than is necessary for this hydration process, it can weaken the resulting paste.

  2. the strength of fully compacted concrete is inversely proportional to water-cement ratio hence on increasing the water cement ratio strength of concert will decrese/

  3. On increasing the water-cement ratio, the strength of cement paste generally decreases.
    This is because the water-cement ratio affects the hydration process of the cement particles, which is necessary for the development of strength.
    When water is added to cement, it reacts with the cement particles in a process called hydration. The chemical reaction between water and cement forms a paste that hardens and gains strength over time.
    However, if there is excess water in the mix, it can weaken the strength of the paste by creating voids and reducing the density of the mixture.
    This is because the excess water can weaken the bonding between the cement particles, leading to a weaker overall structure
