AN EXPERIMENTAL INVESTIGATION ON MECHANICAL PROPERTIES OF MORTAR WITH ADMIXTURE

In regular Practice During the plastering work there is no admixture used in ordinary mortar but actual situation on site is the labour can mix the material at time 10 am and used this material whole day till the end of day time 5.30 pm during this period mortar loss the physical properties of mortar because in mortar consist of cement, sand, water. But cement has its own limitation like initial setting time not less than 30 min & final setting time not more than 10 hrs. But actual practice, material mixing time and actual placing time are varying due to this reason our research focus on the physical properties on mortar and compare with admixture mix mortar. For this experimental study we prepare the ordinary mortar and to check the Properties of mortar in Plastic Stage. Like flow table test and Properties of mortar in Harden Stage like compressive strength and same material mix with admixture in 2% & 5% against the weight of cement. And compare with IS standard.
