While there are many types of cement, Portland cement is the most commonly used cement, and is an ingredient in concrete, mortar, and plasters. Concrete can be purchased in multiple forms, including in 60 or 80-pound bags, or delivered in large amounts by specialized concrete mixer trucks.
· Builders also measure the strength of the resulting concrete in grades. The higher the grade, the stronger the concrete is. The mix ratio of the concrete determines its grade. A concrete grade of M25, for instance, needs a mix ratio of 1 : 1 : 2. This indicates a ratio of one one part cement, one part water, and two parts coarse aggregates.
