Useful information for beginners masons – For centuries, masonry technology have not changed significantly . With a good eye and certain skills , you can learn a simple clutch fast enough. Difficulties arise in deriving the angular designs , but this work can be done with proper quality . The main thing is to determine the type of brick, with regard to this problem . The range of tens, if not hundreds, of names, types and categories . Construction , lightweight , body , facing, insulating ceramics – all building material , wherein the shape , color, volume and many other performance properties .
How to choose a quality brick and mortar ?
The quality and type of brick depends on its cost. Uneconomic use of expensive , high- bricks for the construction of single-storey houses, or use an expensive plaster cladding . One of the advantages of this ancient material is economic viability and freedom of choice , the existing range is able to meet all the requirements of technical conditions . Despite a significant decrease in thermal conductivity of certain types of brick , brick houses heat losses remain high. The problem is solved additional wall insulation, mostly internal or wall-mounted . Internal insulation and wall-mounted glass done , basalt wool Rockwool , polymer inserts, foam polystyrene coatings and aerated concrete panels. Widely used cavitation plate Butts thanks to the high performance characteristics and ease of operation.
The recent hype surrounding imported brick gradually declining. Releasing durable and beautiful brick Western manufacturers do not bother to meet the dimensional standards , the total number of sub-standard size brick, can be from 3 to 5%. Scatter compensated thickening seams, which are given a certain decor . this is not entirely acceptable because almost doubles the heat loss through thermal bridges .
Selecting the planned loads and climatic conditions of the area brick material , care should be taken qualitatively mortar . To date , it is not simply a mixture of cement sand and water . In today’s solutions, the composition includes additives which improve , through which concrete obtains a high moisture and frost resistance , fast curing , elasticity and other equally useful properties.
Quality masonry mortar is largely dependent on the type of cement , sand purity , homogeneity of composition and even the hardness of the water used. Dosing components can only qualified , otherwise risk getting too skinny or fat solution , both versions are used in exceptional cases. To work you must use only the correct proportions of all components .
Freshly prepared solution is desirable to use immediately . Infinite mixing in mixer with periodic addition of water would adversely affect its quality. Exceptions are solutions with anti-shrinkage polymer additives that keep working material for a longer time . Novice amateur masons , experts recommend dry practice skills without the use of mortar. Having clarified the location of rows and vertical joints , ligaments angular device , you can start masonry work .
Throughout the workflow even experienced masons periodically check the quality of masonry plumb and level building . Independent work , these simple tools should always be at hand. Uneven masonry , of course, can be dismantled , but it means a loss of time and money spent on acquiring or preparing concrete solution . Not recommended to compensate for flaws thickening or thinning of the joints , such masonry will look sloppy even under the plaster .
In dry hot weather masonry ready to periodically moisten , moisture needed for accelerated mortar setting . Highly undesirable if a semi- brick structure would be in the pouring rain . Porous structure absorbs a lot of moisture and the walls will long remain raw. In addition, moisture can ruin flowing seams and inner insulation Rockwool , which may lose its insulating properties .
