Sand Base AAC Blocks
Fly Ash AAC Blocks
| Introduction | The traditional member of the AAC family, Sand Base AAC Blocks have superior strength and performance features that make them perfect for a larger variety of construction applications. These blocks utilize sand as the main material, which results in a denser structure and a higher compressive strength. Their increased density results in better sound insulation as well, making the home more comfortable and less noisy. Sand Base AAC Blocks persist as popular choices because of their exceptional fire resistance, strength, and durability. For applications that prioritize fire protection and sound insulation, as well as multi-story buildings and commercial buildings, they provide superior value for strong wall constructions. | When compared to conventional materials like clay bricks, AAC Fly Ash Blocks significantly minimize the environmental effect of building by utilizing fly ash. It is an environmentally friendly choice because less energy is utilized in the manufacturing process and less harmful pollutants are produced. Because of their cellular structure, which is the result of adding a foaming agent, they are extremely light. of the decreased dead load, this results in simpler handling, lower transportation costs, and less stress on the building structure. Because they are lightweight, they are also excellent for locations that are prone to earthquakes and repairs. As Fly Ash Blocks are easy to drill, shape, and cut as required. |
| Definition | Sand Based AAC Blocks is a lightweight porous product made of silica material (sand or quartz tailings) and calcium material (lime, cement), mixed with aerating agent (aluminum powder), through the process of batching, mixing, pouring, pre-curing, cutting, autoclaving and maintenance. | Fly Ash AAC Blocks type of wall material made of fly ash, lime, cement, conditioning agent, and aerating materials, through the process of batching, mixing, pouring, static stopping, cutting, and autoclaved maintenance. Its production process is basically the same as that of sand aerated. |

StarBigBloc’s Star Product: AAC Blocks Building the Future, One Block at a Time
Lightweight
AAC blocks are considerably more lightweight than conventional concrete blocks, yet they preserve outstanding strength.
Thermal Insulation
AAC Blocks are excellent insulators, keeping interiors cool in summer and warm in winter, reducing energy costs.
Soundproofing Properties
With exceptional soundproofing capabilities, AAC Blocks create serene indoor environments by minimizing external noise.
Fire Resistance
Engineered to withstand high temperatures, AAC Blocks provide superior fire resistance, ensuring enhanced safety.
Cost Saving
AAC blocks are nine times larger than red clay bricks, reducing the need for mortar joints by almost 66%. Weighing one-third of a clay brick structure results in a 20% reduction in steel usage and cost savings.
Pest Resistance
AAC's pest-resistant blocks composed of inorganic materials prevent termites from causing damage and losses.
Eco-Friendly
Made from sustainable materials, AAC Blocks contribute to reducing carbon footprint and promoting eco-friendly construction practices.
High strength & Longevity
These are various grades of AAC blocks with different compressive strengths. Depending on the engineering design, higher-grade blocks can support heavy loads, which qualifies them for structural uses such load-bearing walls, columns, and beams.
Earthquake Resistant
Lightweight blocks show exceptional resistance to earthquake forces since the forces exerted by an earthquake on a structure are directly proportional to the building's weight. It has been demonstrated to ensure category 5 tropical cyclone wind loads.
Water Resistant
The lightweight block's microscopic structure prevents capillary action, making it indestructible to water. Additives based on silicone improve its water barrier properties considerably.
Energy Efficient
Because of its high thermal insulation, it reduces air conditioner load by 25% and saves 25-30% on HVAC electricity use.
