Proportions of expanded clay concrete when making with your own hands

Lightweight concrete, sometimes referred to as expanded clay concrete, is an excellent material for many different types of building projects. Expanded clay aggregate, which has great insulation qualities and is lightweight, is used in its construction. This makes it perfect for both professional construction jobs and do-it-yourself projects at home. Expanded clay concrete can be used for wall panels, garden structures, and decorative elements. It is a long-lasting and adaptable material.

It can be a satisfying project to make your own expanded clay concrete at home. You can adjust the proportions to meet your own requirements, and it also provides you with a practical grasp of the subject matter. You have control over the concrete’s strength, density, and insulating qualities by modifying the mix. It is ideal for a variety of applications because of its adaptability.

To get the best results, it is important to get the proportions just right. Cement, sand, water, and expanded clay aggregate are usually combined to create expanded clay concrete. All these ingredients are essential: cement holds the mixture together, sand gives it structure and bulk, water starts the chemical reaction that leads to curing, and expanded clay gives it the light weight and insulation it needs. Comprehending the appropriate proportions of these components will enable you to formulate a blend that is robust, long-lasting, and functional.

We’ll walk you through the process of mixing expanded clay concrete in the ensuing sections, emphasizing important pointers and strategies to make sure everything goes smoothly. Whether you are an experienced do-it-yourselfer or a novice, following our simple guidance will enable you to produce a high-quality outcome. By the end, you’ll be well-equipped with the information and self-assurance needed to take on your own expanded clay concrete projects.

What expanded clay concrete consists of

Any expert will tell you that expanded clay concrete always consists of the following:

• cement;
• sand;
• fine expanded clay made from natural raw materials;
• water without technical impurities.

Crucial! Waste water that has an indicator pH of less than 4 is not at all appropriate for these uses. The same holds true for seawater, which causes the completed surface to get coated in white.

Additionally, sawdust, ash, and plasticizers can be added to the building mixture.

On the construction site itself, a more precise selection of the expanded clay concrete’s necessary composition is made. Additionally, the following suggestions will assist you in obtaining the best combination:

1. To increase elasticity, use quartz sand.
2. To ensure that the finished structure is resistant to moisture, it is recommended to add expanded clay gravel (without sand) to the solution.
3. Portland cement with a marking of M400 is a good binder, without plasticizing components.
4. Cement increases the strength of the finished block, however, it is worth considering that in this case the volume of the mass of the building mixture will be greater.
5. If the finished blocks will be further subjected to heat treatment, it is best to use alite cement.

In the event that we discuss the KB raw material size, then:

• For a moderate density composition, it is best to use coarse-fraction expanded clay. Such solutions very often act as a heat-insulating material.
• Fine expanded clay is suitable for the construction of load-bearing structures.

Practical! The completed product has greater weight thanks to smaller expanded clay granules. Use a combination of large and small "stones" to arrive at the "golden mean".

The size of the expanded clay concrete blocks directly relates to the kind of work you intend to undertake.

Recommendations for preparing mixtures

Before you do it yourself, consider the following advice when making expanded clay concrete:

1. To obtain high-quality KB blocks, you cannot do without a concrete mixer.
2. During the mixing process, a certain sequence of feeding the components is observed. First, water is poured in, then cement, then sand. Expanded clay is added only when these three components have transformed into a homogeneous mass.
3. To increase the KB for tensile strength, use reinforcement.
4. A high-quality solution is considered to be a mixture in which the cement "glaze" completely covers the expanded clay granules.
5. Make sure that one knead does not go for more than 7 minutes. If you mix the design bureau for too long, then its quality will noticeably deteriorate. It is best to stop the concrete mixer, as soon as the composition reaches the consistency of sour cream and there are no lumps left in it.

Wholesome Using a shovel, scoop up the composition to see if the mixture is ready. The ideal proportion of components has been reached if the hill is steady and not blooming; if it blurs quickly, the design bureau is too liquid.

The following concrete brands are most frequently utilized for solutions:

1. M50 – for partitions;
2. M75 – is used as in the construction of the supporting elements of industrial and residential facilities;
3. M100 – if it is planned to build residential low -rise buildings, when warming the enclosing structures or to arrange a monolithic floor of floors and screeds.
4. M150/200 – for load-bearing structures, as well as for the manufacture of wall blocks or panels. This composition can withstand temperature fluctuations and chemical exposure.
5. M200 – more often used to create lightweight blocks and ceilings. This material is resistant to moisture and chemicals.
6. M300 – for road surfaces and bridges.

When discussing expanded clay concrete proportions for various construction projects, it is important to point out a few "recipes."

Expanded clay concrete mixtures in proportions

The ratio and proportions of the ingredients will vary based on the specific purpose for which you are making the mixture.

For blocks

To make KB blocks, combine:

• Mix one part of cement and 2-3 parts of sand.
• Achieve a homogeneous mass and add 0.9-1 part of water.
• Stir the composition again.
• Add 5-6 parts of expanded clay.

You can dilute the expanded clay filler with a small amount of water if it’s too dry. In the event that premium sand is unavailable, "Peskobeton" may be used in its place.

For the floor

If you want to use wet KB screed to cover the entire floor, combine:

• one part cement and the same amount of water;
• 3 parts sand;
• 2 parts expanded clay.

The ideal expanded clay gravel ratio for these uses is 0.5–0.6 m3 of expanded clay for every 1.4–1.5 tons of sand-cement mixture.

For walls

Use this "recipe" to prepare the mixture for the walls:

• one part cement;
• 1.5 parts expanded clay sand (its fraction should not exceed 5 mm);
• 1 part fine expanded clay;

For ceilings

Use the following mixture for this type:

• one part cement;
• 3-4 parts sand;
• 1.5 water;
• 4-5 expanded clay.

Fillers for KB can come in many forms.

Fillers for KB

For these kinds of mixtures, expanded clay or expanded clay sand are not always utilized as fillers. Larger raw materials like gravel or quartz sand can also be added. In this instance, expanded clay itself is the foundation. This justifies the existence of multiple filler types:

1. Angular or rounded gravel.
2. Irregular angular crushed stone with a rough surface, open pores and "porosity".

Bulk density separates expanded clay into 12 grades, but only two of those grades—A and B—are utilized in practical applications.

Making your own expanded clay concrete is a useful and satisfying project. You can create sturdy, lightweight concrete that is ideal for a variety of construction projects by knowing the proper ratios and ingredients. One of the main components, expanded clay, gives this kind of concrete its low weight and insulation properties, making it very versatile.

Accurate component measurements are essential when preparing your own expanded clay concrete. The mixture usually consists of sand, water, cement, and expanded clay aggregate. By varying these ratios, you can get the strength and consistency that you want for your particular project. A typical mixture for most general uses would be one part cement, three parts sand, and four parts expanded clay. Water would then be added gradually to get the desired consistency.

Expanded clay concrete has a number of advantages. Because it weighs less than traditional concrete, it is easier to handle and offers superior acoustic and thermal insulation. Because of this, it’s a great option for creating floors, walls, and even some kinds of structural components. Furthermore, because expanded clay concrete is made with natural clay and frequently contains recycled materials, it is more environmentally friendly.

In conclusion, creating your own expanded clay concrete can help you control the building process and save money. You can produce a high-quality material that meets your construction needs by closely adhering to the suggested ratios and mixing procedures. You’ll get more accustomed to the procedure and gain a deeper comprehension of this adaptable building material with practice.
