Advantages
What are the advantages of instant concrete products that make them a top priority for concreting in construction?
Produk beton cair, umumnya dikenal sebagai beton ready mix atau cor siap pakai, adalah campuran semen, pasir, batu split, dan air yang diformulasikan khusus di batching plant dan dikirim ke lokasi konstruksi dalam bentuk cair siap cor. Produk ini dirancang untuk kemudahan, kecepatan, dan konsistensi mutu yang lebih baik daripada adukan manual
Ready-mix concrete is a mixture of cement, sand, crushed stone, and water that is specially formulated in a batching plant and delivered to the construction site in a liquid, ready-to-cast form. This product is designed for greater ease, speed, and consistency of quality than manual mixing.
Porous concrete combined with colored concrete is a concrete product with a relatively high flow coefficient (80 to 700 liters/m2/hour). Due to its high flow coefficient, this concrete has a porous visual character. Porous concrete can be combined with coloring materials/pigments to enhance its visual appeal.
Porous concrete can be applied to surfaces requiring a closed drainage system to prevent water from pooling during rain. Therefore, it is commonly used in parking areas, sidewalks, jogging tracks, neighborhood roads with light traffic, and areas requiring rapid drainage without closed channels. Due to its porous appearance, the compressive strength of porous concrete is relatively low (it can only be produced in grades K100-K225). The slump of this porous concrete is very low (no slump) due to the use of special additives to bind the particles between the voids.
CTB concrete is used as a subbase layer in road pavement structures (both flexible and rigid). CTB concrete has a zero slump value due to the minimal water usage.
CTB concrete is delivered without a mixer truck, but rather by dump truck, as the pouring and compaction processes are done manually. CTB concrete exhibits a significant volumetric shrinkage, from a loose (loose) state to a compacted state after compaction, with shrinkage of approximately 25% to 30%.
Because it functions as a subbase layer, CTB concrete does not require high compressive strength. CTB concrete is typically produced in grades ranging from low to K-225.
Concrete with the required compressive strength achieved in a short time (less than 24 hours). This is commonly referred to as Rapid Setting Concrete in the Jakarta area.
Qualities commonly used for Fast Track Concrete include:
Design principle: increase the target compressive strength based on the percentage of achieving normal conditions. The use of Type F additives is crucial, as can also be done with accelerators or Type 3 cement (high early strength).
This concrete product meets a relatively high initial compressive strength requirement (accelerated setting concrete). It's also commonly referred to as Rapid Setting Concrete in the Jakarta area. Fast track concrete is typically used on road structures that require immediate traffic opening within 24 hours.
Concrete delivery time from batching plan to project completion is very limited due to the relatively rapid slump loss (maximum delivery time of 1 hour) and a maximum unloading time of 30 minutes.
Self-Compacted Concrete (SCC) is a type of concrete that flows and solidifies without the need for compaction equipment. This type of concrete is ideal for structures with dense reinforcement because it can fill all gaps effectively.
Concrete pumping services are concrete distribution services using specialized pumps to reach high-rise or hard-to-reach areas. This service helps speed up and simplify the casting process.
Mass concrete services involve the provision and management of large-scale concrete casting for large structures such as thick foundations or dams. This type of casting requires strict temperature and quality control
Cold-temperature concrete is concrete produced under controlled temperatures to prevent excessive heat buildup during the hydration process. This type of concrete is essential for large projects to prevent cracking due to temperature differences.
Beton ringan adalah beton dengan berat jenis lebih rendah karena menggunakan agregat ringan. Beton ini membantu mengurangi beban struktur dan sering digunakan pada bangunan bertingkat.
High Performance Concrete (HPC) is a superior performance concrete that has high strength, resistance to aggressive environments, and better long-term performance than conventional concrete.
Colored concrete is concrete with a distinct color appearance from standard concrete. Colored concrete offers an exposed aesthetic, requiring no finishing and can be applied to any structure without fear of color fading when using painted concrete. Colored concrete can be used for pedestrian walkways, dedicated parking lots, exposed walls, highways, and residential streets.
This colored concrete is made with a mixture of special concrete color pigments that do not reduce the concrete's strength. Available pigments in this colored concrete are red, yellow, green, gray, and black. Available in grades K 100-650 kg/cm2.
