essential ingredients of concrete are cement, aggregate (sand, gravel) and water. Concrete blocks are produced in a large variety of shapes and sizes. They can be produced manually or with the help of machines. Most commonly used concrete blocks are sized: Length: 40cm (half blocks: 20cm) Height: 20cm Width: 8/10/15/20cm

For block-making applications, it is best to use types of cement rated at 42.5 or 52.5 since this provides adequate strength gain. Strength gain occurs during the hydration reaction between cement and water. The aggregates used in block …

Size of aggregate used in RCC:- RCC is reinforced cement concrete made of mixture of cement, sand, aggregate and water provided with steel bar. Typically the most common size of aggregate used in RCC structure like roof slab, column, beam and bridge deck is a combination of 10mm, 12mm and 20mm.

Almost all concrete block producers today use aggregate smaller than 1⁄2 inch although scattered reports have indicated the feasibility of using an aggregate with some material of larger size. The maximum size possible will depend on the minimum section thickness of the concrete block.

Sieve sizes commonly used for concrete aggregates are detailed in Table 1, and various physical properties of normalweight aggregates, with typical range values, are shown in Table 2. Coarse and fine aggregates are generally sieved separately. That portion of an aggregate passing the 4.75 mm (No. 4)

sign a two-aggregate, normal-weight block mix with an industry-recommended FM of 3.70. The mixer can handle a total dry aggregate batch weight of 4,500 pounds. Step 1: Aggregate FMs. As indicated in the table be-low, our coarse aggregate (gravel) has an FM of 4.82 and our fine aggregate (sand) has an FM of 2.75. Step 2: Aggregate proportioning.

As a rough guide, using aggregate cement ratio of 8:1 by loose volume, three and a half bags of cement and a cubic metre of aggregate will be enough to make about 400 standard bricks.
