Should choose the bricks which is not shattered after being dropped.- Smash 2 bricks together, if the sound is definitive, sharp, and clear, this is a good quality brick.- Soak bricks in water for 24 hours. Then check the weight of the bricks before and after immersion. If the weight of bricks is 15% heavier, this type of bricks should not be used. For example, a brick weighing 2kg, after being soaked can not weigh more than 2.3 kg, it will ensure the requirements of construction.

2. Cement

Cement is an irreplaceable binder of concrete and mortar, when meeting with water cement helps sand, gravel, stone … connect to form a unified block.During the general development of the cement industry today, the cement is circulating in the market supplied from many different sources. This is both an advantage and advantage, but also causes many difficulties for consumers when there are too many choices.You can preliminary check the quality of cement in the site by the following ways:- Packing date: Manufacturing date will be visible on the bag. It is important that the strength of cement will decrease with age.- Brush: take a little cement and rub with 2 fingers. If quality cement, it will be smooth.- Insert by hand: you have a cool feeling when putting your hand in the cement bag, which means that the quality of cement is not out of date. It has no Hudratification reaction in the cement bag.- Floating test: take some cement into a bucket of water. If it sinks, it is quality concrete.- Odor test: if you can smell the soil, it proves that the cement contains too much clay and mud.- Presence of lumps: there should be no lumps in cement bags.To more accurately assess the quality of a cement, you can ask the sales or manufacturer to provide you with a specific quality certificate of the cement shipment you are interested in. You can compare among the quality certificate of cement companies present or at the same time. You can find out the quality of Long Son Cement products PCB30 and PCB40 here.

Aggregate stone when put into use should note some of the following requirements:- Use of impurities, clean, less impurities to limit the work of workers.- Eliminate impurities in construction stone by sieving through wire mesh or washing with water.

4. Select construction iron and steel

Steel plays a key role in every building, capable of supporting hard and fragile concrete layers. Depending on the use of each type of construction, you need to choose the appropriate iron and steel respectively.

– medium grain sand to build walls and bowl, fine-grained sand used to level the foundation, large grain sand to make concrete.

– You can get a rough idea of the quality of the sand by taking a handful of sand. That way the dirt and mud will stick to your hands. This will determine whether the sand is clean or dirty sand. You should choose clean sand to facilitate the use.

– Check whether the sand is alum or salty before buying to ensure the quality of construction.

6. Water
