The use of fly ash as supplementary cementitious material was originally motivated by its consistent pozzolanic activity and provide for sustainable development in the cement industry. India has been a pioneer in the manufacture of blended cements. Traditionally the blended cements in the country have been produced with calcined clay, mixes of calcined clay and fly ash, fly ash and granulated blast furnace slags. The improved understanding of the beneficial properties imparted by fly ash for both the plastic and hardened stages of blended cement concrete has led to a gradual growth in acceptan ..read more

In the pyro processing of cement raw mix , major attention is given to optimise and control the chemical processes resulting into formation of clinker minerals , as they directly influence cement properties. However , due consideration is not given to control the granulometry of clinker. This property is of immense importance since it determines efficient cooler operation , life of burning zone refractory and Grindability characteristics of resultant clinker . Literature reports many test methods for prediction and assessment of clinker granulometry. However use of these methods is limited , a ..read more

Cement testing as per Indian standards IS: 4031, i.e., primarily determination of Normal Consistency of cements and subsequently gauging of cement mortar is  carried out manually and requires skill and experience for better accuracy, precision and reproducibility. In the changing times with less skilled manpower the manual methods result in issues of reliability and reproducibility  At the authors’ lab, substantial test data were generated, so as to have comparison of cement mortar tests’ results for OPC, PPC & PSC gauged with manual and mechanical mixing (using Hobart mixer) &am ..read more

In a concrete environment the steel reinforcement is chemically passivated by the alkalinity of the concrete cover, the rate of corrosion under ideal conditions is negligible, however due to the  changes in the conditions around the steel reinforcement, the rates of corrosion can reach alarming proportions .  Steel reinforcements is often used in severe environments where soluble chlorides are present . Ingress  of chloride in the concrete surrounding the reinforcements ( coastal environment or in regions where deicing salts are used ) disrupts the passive protective oxide layer ..read more

The availability of limestone deposits containing lower MgO content (< 2 %) is slowly depleting and many cement plants are forced to accept limestone having higher MgO (> 3.0 %) for cement manufacture. Unsoundness problems in cement associated with high MgO content (Periclase formation) are well known and there is a need to study and understand the undesirable effects of high MgO content on the clinker quality. Extensive studies of raw mix design and optimisation have been carried out at author’s laboratory with raw materials from different plants with higher MgO contents. These studies ..read more
