Features and designs of concrete block houses

Concrete houses are the embodiment of the most durable structure. Their service life can reach almost 100 years. Houses built using frame-monolithic technology are close to multi-storey in terms of “capital”.

Advantages and disadvantages

The advantages of reinforced concrete houses are as follows.

  1. Unrivaled strength, durability – thanks to frame-monolithic technology.

  2. Modularity – the house can be either assembled from ready-made blocks, or cast in stages, by adding each subsequent row over the previous one.

  3. Space for architectural research: the frame monolith can be made in any shape. Unlimited imagination for creating arches and lancet transitions borders on another important advantage: the frame and foundation, columns and pillars are connected together.

  4. No need for external finishing: reinforced concrete does not require a ventilated facade, brick-tile cladding. Just painting the walls is enough – once every two years.

  5. House made of concrete blocks well soundproofed.

  6. The structure of concrete blocks is fireproof, not afraid of frost or heat, earthquake resistant, easy to install.

  7. Concrete blocks environmentally friendly.

  8. Number of floors in such a house varies from one to several.

And now we will list some of the disadvantages of reinforced concrete houses..

  1. The frame cannot be started to erect, until the foundation gains strength and shrinks, it takes at least a month.

  2. Walls cannot be erected until the frame, following the foundation, gains strength, and the drawdown of the house will not stop.

  3. The need to water abundantly all reinforced concrete structures for at least 31 days from the day the foundation was poured. For the elements of the frame, this is fully true, since the structure is not erected all at once, each of the elements must be doused with water during the same period. Neglecting to gain strength due to high humidity will significantly shorten the life of the building..

  4. The severity of the entire structure exceeds houses made of wood, foam blocks, hollow bricks and even a stone structure.. A reinforced foundation is required – a concrete grade of at least M-500 and welded reinforcement no worse than A-3C.

  5. The need for thorough waterproofing. The best waterproofing agent is thickened (4-5 mm) roofing material.

  6. Insulation of the house outside is required: in the RC-house it is hot in summer and cold in winter. Reinforced concrete structures support both. Such houses cannot be insulated from the inside – the insulation will become unusable from dampness..

  7. With a surface location of groundwater, concrete moisture permeable.

The same disadvantages are inherent in sand and slag concrete. Concrete buildings – small or, conversely, spacious – conduct heat and cold well.

Nuances of construction

Sand concrete, slag concrete and reinforced concrete private houses adhere to the general principles of construction.

  1. The foundation is necessarily slab-tape (monolithic). An even greater strength and stability will be given to the house by the basement-foundation, with a full-fledged deepening of up to 3.5 m (the depth permitted by law is up to 5). Projects of concrete houses provide for the reinforcement of the foundation with pins of at least 14 mm in diameter (section), with a ribbed surface. The reinforcement is bonded and / or welded before pouring the concrete filling.

  2. Second floor, if it is not made of wood, it is advisable to make it complete. That is, approximately equivalent rooms, according to the project, are located one above the other: a bathroom above the bathroom, bedrooms above the bedrooms, a gym and / or a children’s play area on the second floor above the kitchen-living room, a hall above the hall, a balcony above a permanent canopy, a summer garage or a porch. Hozblok, garage, basement floor workshop are located respectively under the bedrooms, bathroom, kitchen-living room and under the sports room, located on the ground floor.

  3. It is desirable to make most of the walls, but at least half, load-bearing. Redevelopment of window and door openings in a two- or three-story mansion is not allowed – consider everything in advance.

The principle of equivalent floor planning is at the heart of multi-apartment high-rise buildings, multi-storey dormitories and office buildings.

The walls of the floors should be placed strictly on top of each other, without a single centimeter of indentation. Only in this case, the house will last a century or more..

Projects overview

The principle of equivalent interposition of premises, considered in the first of the projects, is not violated as much as it happens in the case of wooden houses or buildings with a wooden attic. One of the bedrooms on the second floor – on the side of the terrace on the first – is supported by pillars designed for this weight. Otherwise, the second and third bedrooms are located one above the other, the fourth is above the study, the storage rooms and dressing rooms are also not displaced so much that the cells on the plan create a threat of accelerated deformation of the frame base. Halls and bathrooms are also located strictly one above the other.

The second of the projects, although not a full-fledged two-story house, has been greatly simplified.. The second floor consists of a single large room. In this case, the bearing walls of the first and second floors completely coincide on the plan. The main living room is located above the main utility block and the outbuilding. Covered parking is located to the side. Total floor area – 277 m2.

Finally, the third project contains the second floor, represented by a single room. In fact, there is almost no second floor – the plan of the first is so complicated that the designer did not complicate the calculation of the permissible load, and made an attic house with a complex sloping roof. Namely – the hall and the bedroom are located above the living room and kitchen, while the load-bearing walls of the second floor are repeated in relation to the first.

Design options

The design of a one-storey (and higher-storey) house, the walls of which are built of sand-concrete blocks or using frame-monolithic technology, needs significant revision. The simplest case is vapor-permeable plaster, the more complex is facing with brick or clinker tiles..

If this is not done, then the design is considered incomplete. Finishing can also be completed with decorative concrete blocks, whose thickness does not differ much from the thickness of the load-bearing ones..

Beautiful examples

The examples below cannot be beautiful by definition until they are finished externally.. However, a roof made of colored profiled sheet will already give the future beautiful house, which is not yet such, a certain look. For example, a brown corrugated sheet is in harmony with leveled walls, which are still gray. The existing look will also be slightly improved by the wooden frame made of boards, which goes under the very edge of the profiled sheet flooring. At the request of the owner, it is varnished – they leave the natural color of the wood, or paint it in a certain color. Whitewashing or painting of walls is performed provided that they are sanded by a master to an almost perfectly even state. Like a conventional cemented wall, the sanded concrete block lends itself to coating with paint or indelible lime.
