Construction from sand blocks

Sand block construction is an inventive and environmentally friendly technique that is becoming more and more common in contemporary building. These blocks, which are composed of sand, cement, and additional materials, have several advantages that make them a desirable choice for a variety of projects.

The affordability of sand blocks is one of their main benefits. They are a cost-effective option for both builders and homeowners because they are usually less expensive than conventional bricks or concrete blocks. Their production method is also more ecologically friendly, which lowers a construction project’s overall carbon footprint.

Their ability to insulate against heat is a huge bonus. Buildings can be kept warmer in the winter and colder in the summer by using sand blocks, which offer superior insulation. This can result in considerable energy bill savings and improve the comfort level of the home.

Sand blocks also have the advantage of being durable. Because of their resistance to fire, weathering, and pests, structures made of them last longer and require less maintenance over time. Their dependability renders them the perfect option for a wide range of construction purposes, encompassing both residential and commercial establishments.

Knowing the benefits of sand blocks will help you, whether you’re a professional builder or a do-it-yourselfer, make wise choices for your upcoming building project. Sand blocks are leading the way towards a more sustainable and environmentally friendly construction industry with their unique blend of affordability, sustainability, and durability.

Types and parameters of blocks

Materials are classified by type based on the existence of cavities:

• Hollow type, providing thermal insulation of buildings, protection from extraneous sounds. They are in demand in the construction of capital walls, easily combined with other finishing materials. The weight of the products is from 8 to 40 kg.
• Solid structure, characterized by increased strength. Used in the construction of foundations, in terms of characteristics corresponds to the parameters of silicate products. Weight – from 100 to 2000 kg.

Table of Sand Block Types and Sizes

The range of applications in construction is impacted by the product sizes. The following size ranges are allowed by the standards for block production:

• length 190 – 500 mm;
• width 90 – 500 mm;
• height 185 – 300 mm.

Sizes and hollowness characteristics of sand (cinder) blocks

The following product sizes are identified:

• length 880, 1180, 2380 mm;
• width 300, 400, 500, 600 mm;
• height 280, 580 mm.

The various types of sand blocks are separated based on their intended use.

• wall, with increased width, used in the construction of walls in one or 2 rows;
• partition walls, have increased moisture resistance. They are used for the construction of interior walls and partitions;
• facing, which do not depend on temperature changes, exposure to moisture, negative natural factors. Used for finishing external wall surfaces.

The spaces between the sand blocks are filled in with fillers. These consist of small crushed stone, slag, expanded clay, and materials mixed with wood shavings and sawdust.

How are cement-sand blocks produced??

Essential elements needed to create sand blocks:

Due to the low cost of raw materials, this ingredient composition enables material manufacturers to provide enhanced performance characteristics while also saving money. Customers are using sand blocks more and more because they are an affordable raw material for building construction.

Semi-dry vibration pressing technology is used in the production process on more productive machinery. The following are the production stages:

• Mixing of raw material components.
• Filling into steel forms.
• Compacting the fraction until homogeneity is obtained.
• Drying of products under infrared rays.
• Standing in a ventilated room with room temperature for 4 weeks.

The primary parameter that the blocks obtain following the last phase is strength. As a result, buildings made of them have a service life of more than 50 years. This lowers the facility’s long-term post-construction maintenance costs. Because of the technology, the weight of the building under construction will not have as much of an impact on the foundation during production because a special filler can be used.

Advantages

The blocks stand out due to their higher degree of sound insulation. They shield occupants from the damaging effects of outside influences. The products can be mixed with other materials, such as insulation, and they satisfy the specifications for raw materials used in construction. They are robust, steady, and long-lasting. Let’s examine the advantages in more detail:

• use in external and internal construction activities;
• increased strength, allowing the construction of foundations;
• high sound insulation coefficient provided by cavities;
• low weight of hollow blocks;

• long service life. The material is not subject to decay, maintains performance characteristics at high humidity, is not susceptible to temperature changes;
• high resistance to high temperatures;
• environmental friendliness, which is based on the use of safe raw materials;
• low price is a plus that customers have appreciated;
• savings during construction, due to the fact that the dimensions allow using one sand block instead of three bricks. The result is the use of less mortar and bricks. Construction of buildings from sand blocks reduces costs by 40% compared to brickwork;
• reduction in the time required to complete construction activities;
• simplicity of masonry, allowing you to build a building yourself without hiring builders.

This material has a few minor drawbacks in addition to these advantages.

Sand block building is an economical and environmentally friendly method of construction. These blocks offer good insulation, durability, and ease of handling because they are made primarily of compressed sand with minimal cement. Sand blocks are perfect for many types of buildings because they provide strong, energy-efficient structures at a lower cost of construction and with less of an impact on the environment.

Disadvantages

Similar to other kinds of building supplies, sand blocks have drawbacks.

• The need to insulate the walls of the room, due to insufficient thermal insulation, especially for northern regions. The material is mainly used for unheated facilities – industrial, warehouse premises, garages, sheds.
• Increased mass of a solid sand block, which requires a solid foundation when used.

Sand block construction is an affordable and long-lasting option for a variety of building tasks. These blocks are perfect for both residential and commercial buildings because they offer superior soundproofing and thermal insulation.

Sand blocks’ adaptability is one of their main benefits. They can be employed for a variety of constructions, such as ornamental elements and walls and foundations. Additionally, because they are lightweight, they are simpler to handle and install, which cuts down on labor expenses and construction time.

Sand block structures require very little maintenance. These structures can endure for decades while retaining their structural integrity and visual appeal with the right maintenance and infrequent repairs.

All things considered, sand blocks are a sensible option for contemporary building since they combine durability, affordability, and sustainability. Sand blocks continue to be a dependable choice for builders seeking performance and efficiency even as construction techniques change.
