SECO BLOCK means SAASCO ECO CONCRETE BLOCK. A Concrete Block is a ‘Building Block’ composed entirely of concrete that is then mortared together to make an imposing, long-lasting construction. These construction blocks can be ‘Hollow’ or ‘Solid,’ formed of ordinary or lightweight concrete in various specified sizes, depending on the precise requirements. Concrete blocks come in various shapes and sizes, and they can be solid or hollow. 39cm x 19cm x (30cm or 20 cm or 10cm) or 2 inch, 4 inch, 6 inch, 8 inch, 10 inch, and 12-inch unit configurations are the most popular concrete block sizes. Concrete blocks are made from cement, aggregate, and water. In concrete blocks, the cement-aggregate ratio is 1:6.

Types of Concrete Blocks:

There are Five types of concrete blocks:
1. Solid Concrete Bricks
2. Two Hollow Concrete Blocks
3. Logo Bricks
4. Uni Paver Block
5. Three Hollow Concrete Blocks

1. Solid Concrete Blocks:
Solid concrete blocks, which are highly heavyweight and formed by aggregate, are primarily utilized in construction projects. They’re sturdy and give structures a lot of solidities. These solid blocks are ideal for large-scale projects such as force-bearing walls. They’re compared to bricks that come in big sizes. As a result, constructing concrete masonry takes less time than brick masonry.

2. Hollow Concrete Blocks:
In masonry construction, hollow concrete blocks are typically employed. It reduces labor costs on the job site while also speeding up the construction process and saving cement and steel. These blocks reduce the natural weight of masonry structures while also improving physical wall qualities like noise and thermal insulation. Standard hollow concrete blocks come in two sizes: Full size and half size. Half-sized blocks are cubical and have one core, while full-sized blocks are rectangular and have two cores. The nominal size of concrete blocks, according to the ‘Research Designs & Standards Organization of Indian Railways,’ is as follows:

i) 390×190x190 mm, Weight : 14.5kg

Hollow concrete blocks come in various shapes, sizes, and designs, depending on the shape, needs, and design.
