Development of Masonry Mortar Using Limestone Polished Slurry and Cement

Abstract

Development Of Masonry Mortar Using Limestone Polished Slurry And Cement Marble processing leaves behind a quarry waste or generally left unattended in the sizing industry. This waste has reached millions of tons as high as that. The main objective of this paper was the use of waste marble slurry as an additive in industrial concrete brick production.

The crushing force was achieved in a range of 7 to 10.5 M Pa. The results conclude that the bricks containing Marble slurry as a raw material prove to be 10 percent less expensive compared to the bricks of the normal mortar mix.

There has been a constant decline in natural resources and an increase in global warming. There has been a widespread increase in the demand for marble products giving a boost to the marble industry.

It has increased the generation of waste in the form of marble slurry during quarrying and processing. Marble slurry can lead to water clogging, increasing top soil alkalinity, and loss of soil fertility. It can also harm the water environment that creates hazards to water animals and plants.

The generated dust can also blanket the surroundings and cause breathing problems. Thus, a widespread need has been observed to make this industry environmentally sustainable.

Conclusion

The results obtained from the above tests show that in order to withstand load, there must be a certain minimum amount of cement (5 – 7.5 percent) along with marble dust in the mix design.

The casted bricks showed positive results, i.e. good compressive strength (7-10.5 MPa) and low water absorption (12-14 %). The cost per brick is also close to that of conventional bricks. This result gives the advantage of achieving higher resistance and use of waste materials at approximately the same cost as conventional bricks.

The bricks without cement and having only fly ash and sawdust as the binding material together with the marble dust can not be casted properly and used for any purpose.
