What are they??

One type of ceramic building material is the large-format ceramic block. Sawdust and baked clay are used to make it. Sawdust creates voids, or pores, during combustion, although some blocks remain impermeable.

For the construction of homes, garages, bathrooms, and other buildings, large-format stone is fantastic. Every product is shaped like a parallelepiped in a rectangular shape.

Such stone ensures long-term stability and durability in construction. Such raw materials can support large loads without overly straining the foundation because of their low weight.

Crucial! Using large-format ceramic blocks eliminates the need for a substantial foundation.

A house built of such material can endure for approximately 150 years if laid correctly, and the products are not contaminated by biological agents.

Their varieties

Large-format blocks can vary from one another in terms of features, dimensions, and other attributes. There is a single distinction between them, known as the "sf factor."

The stone manufacturer uses this feature to show how many bricks of a standard size will fit into a particular product.

Standard dimensions are 65 x 120 x 250 mm. The 10.7 NF and 14.3 NF large-format ceramic block types will be the most popular. The factor shows the number of times the speed of masonry increases when a specific block is used.

Furthermore, the color of large-format warm ceramics varies; they can be yellowish-tinted or red. Additionally, the word "double" large-format block appears in the name. This suggests a double NF factor, so the building material’s characteristics will have the notation "double 2.1 NF."

Citation! Apart from the attributes mentioned earlier, the strength grade of large-format ceramic blocks varies. Additionally, if mineral wool is placed inside the holes, load-bearing walls can be built without the need for insulation.

This article has information on ceramic blocks in various sizes.

GOSTs and requirements

GOST 530-2012 specifies the requirements for large-format blocks, but some European manufacturing facilities even provide higher standards. The GOST specifies several specifications for large-format stone composed of porous ceramics:

• strength – at least M25;
• frost resistance – no less than F35;
• chipping at corners of more than 15 mm – no more than 4 units;
• chips in the corners of less than 15 mm are not regulated;
• cracks in the tongue-and-groove zone – no requirements;
• cracks in the front side – no more than 4 pieces;
• battle percentage – less than 5%.

The editors have recently been debating GOST 530-2019, a new GOST that outlines specifications for large-format porous blocks.

It recommended making some requirements stricter. For instance, it was advised to limit the maximum deviations from the nominal dimensions to a maximum of 5 mm on each of the three sides.

However, this GOST has not yet been ratified or put into operation.

For what types of walls are they used??

Load-bearing external walls of a house are built using large-format ceramic blocks. This can be applied to the construction of apartment buildings as well as low-rise residential properties. Additionally, administrative buildings, saunas, garages, and outbuildings are constructed with this material.

The recommended dimensions for the main external walls supporting floor slabs are 250-510 mm in length, 375 mm in width, and 219 mm in height. These blocks weigh between 15 and 19 kg on average. It is acceptable to use porous ceramics with internal insulation for these uses.

Large-format blocks in other sizes can be used to build internal walls or partitions. In this instance, the stone will be 500 mm long, 80–120 mm wide, and 219 mm high of course. These blocks have a small thickness (4.5 NF or 6.7 NF) in their format.

Since large-format ceramic blocks are not well resistant to frost, they should not be used for wall construction in northern climates where it is typically cold throughout the year.

In the event that this specific block is to be used, ornamental brick must be used to cover the masonry’s facade.

Modern building materials like large-format ceramic blocks are made for sustainable and effective construction. Larger than standard bricks, these blocks are mostly used to construct walls and other structures because of their superior durability, soundproofing, and thermal insulation. Their benefits include lower labor costs, quicker construction times, and increased energy efficiency, which makes them a great option for both residential and commercial buildings.

Main characteristics of the stone

Large-format ceramic blocks have several features, including:

• water absorption – 11-14%;
• frost resistance – F35-F50;
• thermal conductivity – from 0.14 W/(m°C).

The stone’s size varies:

• 380x250x219 mm;
• 440x250x219 mm;
• 510x250x219 mm.

Such building materials have an average strength of M100–M125.

The high percentage of voids (approximately 59%) in the stone structure is what allows for good heat retention rates. Additionally, since mortar is not required in vertical joints, there is a tongue-and-groove system that lowers heat loss.

Features of laying such porous ceramics

Large-format stone installation requires adherence to a few guidelines. For instance, it’s crucial to make sure that the seals between two neighboring blocks are tight. If you overlook this detail, "cold bridges" will appear when the house is being operated. Large-format product walls come in a variety of options:

• wall made of ceramic block with brick lining;
• wall made of block and plaster facade;
• blocks and insulation on the frame.

During the winter, the "wall pie" option is chosen based on temperature readings. Lay the stone on a particular heated perlite solution. The foundation must be waterproofed before the first row can be installed using a cement-sand mortar.

Pros and cons of use

Those who have previously constructed a home with this material can identify several key benefits:

• energy efficiency;
• durability;
• wear resistance;
• strength;
• low water absorption;
• vapor permeability;
• good sound insulation;
• ease of construction.

Owners of these homes mention the large size and weight of the stone, along with the high cost of the products. There is also the additional expense of plastering the inside of the wall.
