Concrete Precast Concrete & Eklusif
The use of concrete Eklusif Concrete-exclusive is is normal range of concrete concrete except as prevalent everyday which is often made from a mixture of Portland cement and aggregate natural and embodied conventionally. Exclusive presenting concrete concrete advances in technology that are maximized to cope with shortages which belonged to normal concrete.Some variety of a concrete that could be characterized as exclusive concrete of which is:
1. Lightweight Concrete (Lightweight Concrete) was made by applying a lightweight aggregate or combined with normal aggregated in such a way so that the created concrete with smaller weight (lighter) than normal concrete. The weight of the contents of the concrete lightweight concrete of 2/3 drove normally. The purpose of the application of concrete masonry is to reduce the weight of the structure itself so that part of the structure of pensupportnya such as the Keystone will be more frugal.
2. high quality Concrete (High Strength Concrete precast) Concrete compressive strength of 40 MPa have bias are classified as high-quality concrete. This maximized to raise concrete structure that demands a high level of interest such as bangunan2 with a high level of security like bridges, tall buildings, nuclear reactors and others.
3. Concrete with high workabilitas (High Workability Concrete) is often the level of distress in the way of concrete work is linked with the level of its alloy keenceran or uniting flowing (flowing consistency), kian dilute concrete will be more easily to run. But don't get me wrong, I meant not merely dilute dilute the cause be given plenty of water, thus with most of the water quality of the concrete will cause low kian penyusunya material can be fragmented (segregated). What is meant here is concrete that flows easily, but consistently has good qualities such as normal or high quality concrete.
4. Concrete Fibers (Fiber Reinforced Concrete) is a concrete its material coupled with the fiber part can be steel, plastic, fibre glass or fibers from natural material. Even though the fibers in the mixture is not too much concrete to increase energy pull style, behavior of concrete structures such as the great increase of accumulating consistent strain that is before ambrol, increasing the durability of the concrete to the clash and add hard concrete.
5. Concrete with Polymer (Polymers Concrete) with the granting of an extra glue materials as polymers in concrete mix, concrete will be created with strong press higher and in less time. Materials that are added can be either latex Emulsion or of other materials. This type of worthy professions was applied to pembetonan in emergency situations such as tunnels, mines and other professions that require concrete energy in a short time even in a matter of hours. In addition, a variety of polymer concrete can be realized with the aim to increase resilience to certain chemicals. There panambahan polymer system except in the concrete mix, can also be carried out on when the concrete has dried up with the aim to close the pores of the concrete and a small crack (microcrac) for drying concrete obtained so watertight (inpermiable) so that the durability of the concrete can be increased.
6. The weight of Concrete (Heavyweight Concrete) the opposite of light weight concrete is concrete, where it had a variety of heavy concrete contents higher than normal concrete (2400 kg/m3) approx. 3300 kg/m3 up to 3800 kg/m3. Heavy concrete is often applied on such buildings for the protection of nuclear installations, biology, health unit and the accounts of the Atomic Research and testing facilities. Concrete weight realized by applying heavy aggregates such as iron ore or natural material.
7. Large concrete (Mass Concrete) is a massive structure with concrete with volume that is really huge as in dams, floodgates or beams and huge pillar and massive. Concrete weight realized by different treatment with normal concrete considering the incidence of excessive heat on the concrete mix and the occurrence of changes in volume which also became really big. Treatment for heavy concrete handling can be implemented by changing the composition of the mixture as a reduction of cement, the addition of additives forming air bubbles and the application of the aggregate which has high density.
8. Concrete Compaction Rollers (Roller Compacted Concrete) on big professions and special like concrete roads and dams, the mandatory concrete compaction is carried out by applying the roller vibrators.
For compacting with rollers, concrete mix mandatory dry enough so that the roller is not teggelam tatapi consistent mandatory have runny so that the distribution of materials (cement) to glue all the surfaces of the aggregate becomes evenly.
How To Use Precast Concrete Construction
Precast concrete became one of the great construction deployment materials to speed up the profession of konstrusi, variable deployment time savings will stand out in earnest once the break we'll apply for precast concrete the construction profession. According to studies done by the "centre prefabrication technology of Singapore". Labour requirement in precast concrete construction is 46.5% less than in conventional construction method (Tan, 2000). Following some plus points where they have applied the concrete construction, among others:
1. Reduce the time variable and variable rates
In the deployment and calculation of variable time and varibel fares, precast deployment becomes a deduction factor two. In terms of the variable time, hence with precast system deployment can therefore abbreviated time making and printing of precast that can run outside the construction zone, and upon arrival can be instantly installed constant worthy with frame structural and its frame such things so no pesky time frame construction where they have run. Precast concrete also seriously save energy deployment work and rate tools and consumable compared had done on its own.
2. Maintain conformance quality and load capacity
Precast concrete produced in in worthy plants by applying the techniques and machineries. Raw materials such as concrete, sand bars and prestressing strands are under high level of quality control. The use of formwork that seharunya better than in site will help to maintain the quality of shapes, and better finishes in precast components. Precast quality is guarded with a predefined standard fitting has a better crack control, offering better protection from harsh weathers and soud insulation.
