Learn MoreOrdinary Portland cement (OPC) is the commonly used cement around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. The Ordinary Portland Cement is mainly c ategorized into three types, which are 33-Grade Cement, 43-Grade Cement, and 53-Grade Cement.

Learn MoreASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.

Learn MoreDifferent Grades of Concrete explained Different projects often require different grades of concrete. In this instance, t he g rade is defined as the strength and composition of the concrete based on the minimum strength the concrete needs to be after 28 days following initial construction.. C Grade concretes are measured using cubic concrete testing.

Learn MoreCement is an essential construction material, which is extensively used in the modern-age of construction. Cement is a prominent ingredient for concrete, mortar, and plaster, etc. Cement is available in different grades. The strength of the concrete mix is dependent on the grade of cement.

Learn MoreThe Concrete Polishing Council classifies finished gloss levels in ranges from 1 through 4 and aggregate exposures as A, B, C or D, depending on the degree of exposure. For coarse grinding, you'll generally start out using diamonds embedded in a metal matrix. As you begin to polish the floor in successive passes, you'll typically switch to

Learn MoreThe nominal mix grades of concrete are generally used for small-scale construction where concrete consumption is not so high. Besides the design mix concrete are those whose mix ratio proportions are obtained from various lab tests by considering the various process in concreting properties of concrete and quality of material used for the preparation of concrete.

Learn MoreIS 456-2000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. In this designation the letter M refers to the mix and the number to the specified 28 day cube strength of mix in N/mm 2 .
