Compute for the quantity of 4” concrete hollow blocks (CHB) needed for a wall that is 3 meters high and 2 meters long. SOLUTION. Determine your initial wall area: Square Wall Area = Length * Height = 2m * 3m = 6m 2. Determine door and window areas: There are no specified doors or windows. Get your total wall area:

Vertical and horizontal layers of the wall will be computed by dividing the wall's height (length) by a unit CHB. The total number of CHB will be the product of the vertical layers by the horizontal layers.

Determine the CHB thickness used for your wall: Concrete hollow blocks (CHB) vary in sizes. Local hardware stores usually have 3 commercially-available CHBs that vary in thickness – 4”(10cm), 6”(15cm) and 8”(20cm) .

The document provides information on estimating masonry works, including: (1) Calculating the number of concrete hollow blocks (CHB) needed based on the total wall area. (2) Determining the cement and sand required to fill the hollow cores of CHB using either a volume or area method.

2023年10月1日 · In this comprehensive guide, we will delve into the details of CHB, its uses, benefits, and much more. 1. Understanding CHB – The Basics. 1. What Does CHB Stand For? 2. Composition of CHB. 2. The Role of CHB in Construction. 1. Structural Integrity. 2. Insulation. 3. Cost-Effective. 3. Applications of CHB. 1. Residential Construction. 2.

It lists specifications for concrete block walls with 4 inch blocks requiring 1911 blocks, 179 bags of cement, and 91 pieces of #10 rebar. It also provides specifications for a 2-way slab with a thickness of 150mm, class B mortar mix, and requiring 5 bags of cement and 9 pieces of rebar.

Determine the 10mm vertical and horizontal reinforcement fr the CHB wall 4.0m length and 3.0m high. Reinforcement is spaced at 80cm on centers vertically and every three layers respectively.

2023年11月5日 · Concrete hollow blocks (CHB) play a crucial role in masonry construction in the Philippines. They are widely utilized for reinforcing building structures due to their numerous benefits. CHB offers a solid foundation for construction projects, ensuring the long-term durability and strength of buildings.

2015年7月29日 · Standard strength for CHB is 500 psi for Bungalow up to 4 Storeys and 700 psi for High Rise Construction. Walls in 700 psi CHB is considered as load bearing. Because hollow blocks are a common material, non-professional people take them for granted in the site.

This document provides a wall estimate for external and internal concrete block (CHB) walls of a building with 4 floors and a roof deck. It includes the wall dimensions, number of CHB blocks required, reinforcement bars, horizontal ties and material quantities needed.
