Today, lightweight bricks are more favorable than bricks and bricks because they have certain advantages. Among them such as light weight, shape precision, and the price was tilted. Construction of the wall using hebel also does not require any more plaster, but directly can be in aci. So it can save budget plan cost.
Lightweight brick is made from a mixture of quartz sand, cement, lime, a little gypsum, and aluminum paste. This brick is a kind of brick made in a modern factory. In contrast to the conventional red bricks made manually by the hands of workers. This brick became the idol of building contractors and began to be widely used in housing
Special mold of lightweight brick
- Bucket
- Cement spoon
- Hoe
Materials needed :
- Cement as a binder
- Sand as filler material
- Fly ash as filler material
- Lime as filler material
- Water as a diluent
- Pasta aluminum as a developer material
How to make :
Create a hebel mix first consisting of a binder and filler with a ratio of 1: 2. Please note, the meaning of the binder is cement while the filler is a mixture of sand, fly ash, and lime. If you only use fly ash or lime or mix both without sand, then the permissible filler composition is 17% of the total mortar hebel.
Pour enough water into the hebel blend to dilute it. The addition of this water should not be too much or too little because it can damage the quality of the resulting light brick. In general, the amount of water added to the hebel as much as 0.4-0.6 of the total cement used.
The stirring process should be worked out until the composition of the mixing material is completely blended. The nature of the mortar also appears to be homogeneous and the density of its kind is also in accordance with the plan ranging from 1.8-2.2 kg / liter. If the hebel type of mass is not appropriate, you can add water as needed.
After a light brick mix is finished, the next is to form it by using a special mold. The trick is to pour the slurry paste into the mold, then spread the entire surface. In order to dry and print perfectly, leave this mold for about 12 hours.
The next day, open the lightweight brick mold carefully. Next move the hebel-hebel is still raw to the drying (curing area) is open but protected from direct sunlight.
Forms of care that should be applied to lightweight bricks during the drying process include watering the hebel for 10 consecutive days. This is so that the drying takes place slowly so that hebel does not suffer damage or crack. Then on the 15th day, this lightweight brick can be placed in the storage warehouse. The new hebel material may be worn after it reaches more than 20 days from the start of manufacture.
Excess Lightweight Hebel Celcon
As the name implies, lightweight brick has a light weight that does not burden the structure. If using ordinary brick, it will be more difficult to do the addition of the floor or increased the house, because it is feared the structure is not strong. As for the lightweight brick, the structure risk is not strong smaller.
More waterproof
Bricks made in this factory are declared more waterproof, so the house will be more resistant to humid rainy weather.
No need to be plastered
The form of lightweight brick is very smooth because it is done by a factory machine that has a standard product. Therefore, the appearance of lightweight brick that has been installed by itself look fine. Naris are not required plasteran for this lightweight brick. However, plastering should still be done to protect the wall material from rain water seepage and bad weather.
Quick installation
Because of its precision and mounting using instant mortar or adhesive, the process of lightweight masonry work is faster. The size is bigger, that is dimension 60 cm x 20 cm. The thickness varies, from 7.5 cm to 15 cm.
Installation is cleaner
Unlike conventional brick pairs that require a mixture of mortars from sand and cement, hebel blocks require only instant cement mixed with water. As a result, the installation is cleaner and more practical, avoiding sand spots.
Lack of Lightweight Bricks
The price is more expensive
With all the qualities and advantages, the lightweight brick is priced at a price higher than the red brick convensiona. Purchases must be in large quantities. This of course increases the cost of construction that must be spent, especially if it is needed just for a little renovation part.
Requires an experienced craftsman
Lightweight brick installation is different from regular brick work. Roskam used was different, ie roskam toothed. Therefore, it takes a more skilled builder and has experience in installing a hebel brick. You should first check whether the contractor used is experienced in installing this hebel brick.
# Only sold in large stores / distributors
Unfortunately, until now hebel block can only be found in department store building materials or large distributor store only. Contractors or regular contractors of bricks in regular sellers have to switch to large stores.
Need a special, more expensive adhesive
To install hebel block requires different adhesives, ie mortar or special instant cement. The price is of course more expensive when compared to the usual mortar mixture of cement and sand.
The drying process is longer
If these light bricks get too wet from the rain, then the drying process takes a longer time.
