Overview

This document provides detailed dimensional specifications and physical properties for various typical concrete blocks used in construction, including 3 inch (75mm), 5 inch (130mm), 7 inch (178mm), 9 inch (228mm), and 11 inch (280mm) blocks, as well as block flooring.

Block Dimensions and Sections

For each block size, the document presents measurements in millimeters across three views: Plan, Transverse Section, and Longitudinal Section. These views illustrate the block's shape and structural features.

Typical Block Sizes and Key Dimensions

• 75mm (3 inch) Block: Dimensions include thickness of 75mm with detailed sectional measurements; volume approximately 0.00643 m³; self-weight about 11.60 kg.
• 130mm (5 inch) Block: Dimensions include 130mm thickness with detailed sectional measurements; volume approximately 0.0112 m³; self-weight about 15 kg.
• 178mm (7 inch) Block: Dimensions include 178mm thickness; volume approximately 0.0095 m³; self-weight about 18 kg.
• 228mm (9 inch) Block: Dimensions include 228mm thickness; volume approximately 0.0125 m³; self-weight about 19.5 kg.
• 280mm (11 inch) Block: Dimensions include 280mm thickness; self-weight approximately 21 kg.

Block Flooring

Separate dimensions are provided for block flooring, with sectional views and measurements indicating thickness and layout. The flooring blocks have a volume of approximately 0.00643 m³ and a self-weight of 11.60 kg.

Physical Properties

• Volume: Ranges from approximately 0.00643 m³ for smaller blocks to 0.0125 m³ for larger blocks.
• Self Weight: Varies from 11.60 kg for 75mm blocks up to 21 kg for 280mm blocks.

Additional Notes

• All dimensions are provided in millimeters.
• Sections include detailed measurements of block thickness, length, and height, as well as internal features such as voids or reinforcement spaces.
