After preparation, the mortar should be consumed as early as possible. The lime mortar should be consumed within 36 hours after its preparation and it should be kept wet or damp. The cement mortar should be consumed within 30 minutes after adding water and for this reason, it is advisable to prepare cement mortar of one bag of cement at a time.
ratio of cement sand and aggregate in concrete
Oct 26, 2017· When the weight of cement is more, i.e. aggregate cement ratio is less, the concrete has more cement paste required to coat aggregates and fill the voids between them. This more cement paste makes the concrete relatively easy to mix, place and compact as it reduces the friction between aggregates and allows its smooth movement.
Aggregates - Portland Cement Association
Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete.
