Concrete and Cement are the most widely used building materials in the construction industry for over 100 years. Over the years, this construction material has been enhanced and developed to fit to the usage and requirements at site. Several researches are happening around this topic to increase the durability, strength and performance of this building material.
The size of the particles of the cement is its required fineness of good cement is achieved through grinding the clinker in the last step of cement production hydration rate of cement is directly related to the cement particle size, fineness of cement is very important.

Test To Check Fineness Of Cement ... Procedure to determine fineness of cement i) Weigh approximately 10g of cement to the nearest and place it on the sieve. ii) Agitate the sieve by swirling, planetary and linear movements, until no more fine material passes through it.
The aim of the designer should always be to get concrete mixtures of optimum strength at minimum cement content and acceptable workability. ACI Mix Design ACI Mix Design ACI Mix Design AirEntrained Concrete One of the greatest advances in concrete technology was the development of airentrained concrete in the late 1930s.
Feb 28, 2015· Free Powerpoint Templates Page 5 • The fineness of cement has an important bearing on the rate of hydration, rate of gain of strength, evolution of heat. • Finer cement offers greater surface area. • Disadvantage of fine grinding is that it is susceptible to air set early deterioration.
Concrete Mix Design Definition Concrete mix design is defined as the appropriate selection and proportioning of constituents to produce a concrete with predefined characteristics in the fresh and hardened states. In general, concrete mixes are designed in order to achieve a defined workability, strength and durability .
o Most of the cement particles have a size of between 2 and 80 μm. o The surface area per unit weight values of most cements in common use range from about 300 to 400 m2/kg. o The fineness of cement affects the rate of hydration and thus the rate of strength gain o Greater fineness increases the surface available for hydration, causing greater ...
