Each type is mixed with a different ratio of cement, lime, and sand to produce specific performance characteristics such as flexibility, bonding properties, and compressive strength. Vm =Vbw_Vb 9. With the use of strong mortar, cracks will be fewer and wider, while with weak mortar, cracking will be distributed as thin hair cracks. Shrinkage in mortar is less, thus less liable to cracks due to shrinkage. 3. Curing is absolutely necessary to achieve the maximum strength and to get the maximum coating of the available cement around sand particles. Mortar is a workable paste which hardens to bind building blocks such as stones, bricks, and concrete masonry units, to fill and seal the irregular gaps between them, spread the weight of them evenly, and sometimes to add decorative colors or patterns to masonry walls. Block work requires a richer mixture than for brick. Lime has a good water retention capacity and does not evaporate quickly. Of bricks = brickwork volume/ volume of one brick with mortar, Now we calculate volume of brick without mortar =0.230×0.115×0.075 m3=0.00198m3 Repointing brickwork, also known as pointing or tuckpoint, is a means of removing damaged mortar and replacing it.

One bag cement is 50 kg defects in mortar during brickwork construction are found to be: 12. Bonding of lime mortar with bricks is better. Addition of pozzolana increases the strength of the mortar and makes it more resistant to chemical attacks. When fineness of sand increases, the workability of the cement-mortar mix increases, but also increases the surface area of the sand for which requirement increases for cement and water quantity for the same strength. The properties, strength and uses of these Depending on their function, longer shelf life and strength, many brands are available in the market with a price tag of Rs150to Rs700 per 50 kg bag of ready mix Mortar. The ratio to mix mortar is historically accepted as 1:3 of sand and cement. That means, the strength of brickwork depends on the strength of bricks. Become VIP Member. Mortar: This is primarily a mixture of sand and cement (can also include lime) that is used to bond brickwork and blockwork together to form walls and other structures. proportioning of cement sand in mortar provides consistency in the performance and appearance of masonry construction. © 2009-2020 The Constructor.
