Cement hollow blocks (CHB) and Cement grills

hollow units are known as concrete or cement block(CHB). Cement hollow blocks are specified by their nominal dimensions. The nominal dimension is greater than its specified dimension by the thickness of the mortar joint, usually 10 mm. For example A 200 x 200 x 400 block has an actual width of 190 mm, height of 190 mm, and length of 390 mm.

Types of Concrete Blocks Used in Construction | BigRentz

Hollow concrete blocks come in three grades: Grade A has a minimum density of 1,500 kg/m3. Grade B has a density of less than 1,500 kg/m3. Grade C has a density greater than 1,000 kg/m3. Grades A and B are used for load-bearing concrete block walls, while grade C is used for non-load-bearing walls. Hollow blocks come in several types, which are ...

What To Know About Load-Bearing Walls | The Family Handyman

Walls that run perpendicular (at a 90 degree angle) to the ceiling joists are load-bearing. Walls that run parallel (in the same direction) as the ceiling joints are non load-bearing. Ceiling joists are spliced over the wall. Interior load-bearing walls will often have the ends of ceiling joists meet and overlap (AKA splice) over the wall.

Concrete Block (CMU) Sizes, Shapes, and Finishes - Archtoolbox

Concrete Block (CMU) Sizes. Concrete Masonry Units (CMUs) are manufactured in a variety of sizes. They are identified by their depth – i.e. the thickness of the wall they create. For instance, a 6" CMU is nominally 6" deep while a 10" CMU is nominally 10" deep. Concrete blocks also come in half-sizes, which are helpful in reducing the need to ...

ASTM SPECIFICATIONS FOR CONCRETE MASONRY UNITS - NCMA

Currently, seven ASTM standards apply to units intended primarily for construction of concrete masonry walls, beams, columns or specialty applications (see Table 1).

Load-Bearing & Non-Load Bearing Walls: What's the Difference? (Explained)

Load-bearing walls support the entire weight of the floor or roof structure above them. Non-load bearing walls do not bear any weight. Load-bearing walls are essential for supporting floors and roofs. Non-load bearing walls are used to separate rooms or offices. You can tell if a wall is a load-bearing by looking at the studs.

GROUTING CONCRETE MASONRY WALLS - NCMA

Grouted concrete masonry construction offers design flexibility through the use of partially or fully grouted walls, whether plain or reinforced. The industry is experiencing fast-paced advances in grouting procedures and materials as building codes allow new opportunities to explore means and methods for constructing grouted masonry walls.

The Dimensions of the Hollow Part of a Concrete Block | eHow

A 12 x 12 x 8-inch sash block has a single, slightly offset core measuring 4 4/16 inches wide by 8 5/8 inches long. In addition to the hollow core, a 12-inch sash block also has a 3/4 inch square notch running up the entire height of a long-sided face. The notch is located 7 7/16 inches from the left side of the block.

The face shell for 16" length is 1.50" thick which conforms also to the same standard. The overall net area of the CHB is 0.041

Standard Wall Thickness – How Thick Should the Wall Be?

In standard homes, interior walls are framed with 2-by-4 timber, which will have a width of three and a half inches. Drywall will then be fixed to both sides of the frame, measuring half an inch on each side. Therefore the total thickness of an internal wall in most homes will measure four and a half inches. This is the standard width for walls ...

Concrete Block Calculator

To do so, you need to multiply the wall's height and width: wall size = wall height × wall width. To calculate the number of blocks, you need to divide the total area of the wall by the area of a single block: number of blocks needed = wall area / block area. block area = block height × block width. Then you need to calculate your concrete ...
