EXPERIMENTAL STUDIES ON FIBER BASED CEMENT MORTAR CONTAINING FLYASH AND M-SAND
Publication Date : 19/03/2019
In this present experimental investigation, the influence of fly ash, M-sand and polypropylene fibers on strength and durability properties is investigated. About 20% of cement is replaced by fly ash, replacement of natural sand by M- sand in proportions of 50% and 100% and polypropylene fibers of dosage 3.6kg/m3 is employed for 1:4 cement mortar mix. Strength and durability properties such as, acid resistivity (12% concentration H2SO4) and alkaline resistivity (12% concentration Na2SO4) were evaluated for all the mixes of cement mortar and pull off test is carried out.Thriveni M-sand (Plaster sand) is one of the alternative to fine aggregates in mortar. In present investigation compressive, flexure, tensile strength also durability of cement mortar is studied for 1:4 mortar mix with cubes, briquette samples and prisms tested at the age of 7,14 and 28 days. After 28 days of curing durability of all the cement mortar mixes is tested after exposing the samples for one month in acid and alkali solutions, in addition to pull off test on the plaster work is carried out after 28 days of curing in water for all the cement mortar mixes which is considered in this research work.
