The water-cement ratio should be below 0.5/1.0. Cement mortar must be mixed just before use so that it does not cure prematurely. okay, so this is the very important topic. For bedding under the slabs use 5 parts sharp sand, 1 part soft sand and 1 cement. The strength of this concrete mix is determined by the proportion on which these cement, sand, stones or aggregates are mixed. All of us know that sand is the most customary aggregate additive that works very well with cement. The strength of the cement-paste depends on the relative proportions of water and cement; a more diluted paste being weaker. It is typical to start with a basic concrete mix design that is similar to the new mix that is being created. Workability can be resolved with the use of plasticizers or super-plasticizers.. Often, the ratio refers to the ratio of water to cementitious materials, w/cm. Lime is also a common additive to the mix. A low ratio means higher strengths, a high ratio means lower strengths. you here the very important topic for today….t.
