Different Types of Blockwork Concrete

Fair Faced Blockwork

Fairfaced blockwork refers to the construction technique where concrete blocks are laid and finished in a way that achieves a smooth surface without the need for additional cladding or plastering.

Fairfaced blocks are medium-density concrete blocks featuring a smooth and finely-textured surface. These blocks are known for their durability and strength, making them suitable for a wide range of building types, including academic, commercial, and leisure projects. With their low-maintenance requirements, fair faced blocks provide an excellent background for heavy-duty fixings. They offer a reliable and aesthetically pleasing solution for creating visually appealing structures.

Core Filled Blockwork

Core filled blockwork is a construction method that involves using concrete blocks with hollow cores, allowing for internal connections within the wall. This technique utilizes the hollow cores by drilling a hole through a block several rows up, inserting a piece of steel rebar into the core, and subsequently filling it with concrete. By reinforcing the cores with steel and filling them with concrete, the overall strength and stability of the blockwork are significantly enhanced. This combination of materials creates a solid and robust structure capable of withstanding heavy loads and providing structural integrity.

Core Filled Blockwork involves the use of concrete blocks with hollow cores. In this method, the hollow cores are filled with concrete or grout, typically by drilling holes through the blocks and pouring the concrete or grout mixture into the cores. The filling of the cores enhances the overall strength and stability of the blockwork, making it suitable for load-bearing walls or structures that require additional reinforcement. The primary focus is on reinforcing the hollow cores with concrete to improve the structural integrity of the blockwork. Core filled blockwork is commonly employed in load-bearing walls and other structural elements where added strength and reinforcement are required.

Reinforced Blockwork

Reinforced Blockwork, on the other hand, refers to the incorporation of steel reinforcement bars (rebar) within the blockwork. In this technique, steel rebars are placed either horizontally or vertically within the blocks or within the cavity cores. The purpose of the reinforcement is to add tensile strength to the structure, as concrete itself is strong in compression but weak in tension. The reinforcement bars act as a structural support system, enabling the blockwork to withstand greater loads, resist cracking, and enhance overall stability. Reinforced blockwork is often utilized in areas that require enhanced structural stability, such as high-rise buildings, bridges, and other large-scale constructions.

The key distinction between core filled blockwork and reinforced blockwork lies in the primary method of reinforcement. Core filled blockwork focuses on reinforcing the hollow cores with concrete, while reinforced blockwork involves the incorporation of steel reinforcement bars to provide additional strength and stability to the structure. Both techniques aim to enhance the load-bearing capacity and durability of the blockwork, but they utilize different materials and reinforcement approaches to achieve these goals.

Lightweight Blockwork

Lightweight blockwork refers to blocks that are manufactured using lightweight aggregate materials, such as expanded clay, shale, or lightweight concrete. These blocks have a reduced density compared to traditional concrete blocks, making them easier to handle, transport, and install. Despite their lower weight, they still offer sufficient strength and durability for various construction applications.

Aerated Blockwork

Aerated blockwork, also known as autoclaved aerated concrete (AAC) blocks, is a lightweight and highly insulating type of blockwork. These blocks are made by introducing air bubbles into the concrete mixture during the manufacturing process, resulting in a cellular structure. The air-filled voids make the blocks lighter in weight while providing excellent thermal insulation properties. Aerated blockwork is commonly used in both load-bearing and non-load-bearing walls.
