initial setting time of cement
Overview. Initial setting time is that time period between the time water is added to cement and time at which 1 mm square section needle fails .Theory: In actual construction dealing with cement paste, mortar, concrete, certain time is required for mixing, transporting and placing. During this time the cement .SCOPE: In this test we will cover the determination of Setting time of cement by means of the Vicat Needle Apparatus. APPARATUS : a..It caused set retardation of the three different types of cements used, but with one type of cement it accelerated, the initial setting time and retarded the final setting .Niel, ACI [1] / [2]defines set, initial — a degree of stiffening of a mixture of cement and water less than final set, generally stated as an empirical value indicating .It stiffens and sets. The setting process is arbitrarily divided into stages, time of initial setting and time of final setting, depending on the resi...
