Bulk cement is a type of building material often used as an adhesive for other materials, such as concrete blocks and bricks, during construction or house renovation. Its application in construction can be tailored to the consumer's needs.
There are various types, each with different applications. To learn more about what bulk cement is and the different types available at Semen Merah Putih, read on to the end.
What Is Bulk Cement?
Bulk cement is a specially produced type of cement made from various kinds of cement and is common as a building material for both general and specialized construction projects. Currently, many types of bulk cement are marketed and distributed across various regions in Indonesia, including Semen Merah Putih.
Bulk cement is cement that is not packaged in bags but is delivered in bulk using specialized transportation, such as silo trucks, tanker ships, or dedicated trains. This type of cement is typically used in large-scale construction projects, such as high-rise buildings, bridges, highways, or factories, where the demand for large quantities of cement is more efficiently met in bulk form.
Types of Bulk Cement
Semen Merah Putih produces various types of bulk cement. Here are the types and their explanations:
1. Type 1 Portland Cement
Type 1 Portland Cement is divided into three other types: Semen Merah Putih Ultramix-G, Semen Merah Putih Ultramix-P, Semen Merah Putih Ultramix-A, and Semen Merah Putih Ultramix-F. The explanations are as follows:
a. Semen Merah Putih Ultramix-G
Produced according to SNI 2049-1:2020 Type-I, this cement is designed for general construction that does not require special conditions like low heat of hydration and sulfate resistance.
It can be used for precast and ready-mix concrete applications with optimal strength development and good workability. Therefore, Semen Merah Putih Ultramix-G is suitable for building roads, buildings, bridges, and other infrastructure.
b. Semen Merah Putih Ultramix-P
This Portland cement adheres to the SNI 2049-1:2020 Type-III. Semen Merah Putih Ultramix-P is designed for constructions that require high early strength and is suitable for producing high-strength concrete in the precast industry.
This cement enhances productivity in prestressed concrete, precast, and other cement-based industries that need high early strength development.
c. Semen Merah Putih Ultramix-A
This Portland Cement is designed for industries that require fast setting times. Produced according to SNI 2049-1:2020 Type-I, this type of cement improves productivity in the lightweight block industry (Autoclaved Aerated Concrete).
d. Semen Merah Putih Ultramix-F
This Portland Cement is ideal for cement-based industries requiring a certain level of fineness to enhance production efficiency, such as corrugated asbestos roofing, fiber cement boards, and silicate boards. Semen Merah Putih Ultramix-F is produced according to SNI 2049-1:2020 Type-I.
2. Type 2 Portland Cement
The product included in Type 2 Portland Cement is Semen Merah Putih Ultramix-II. This cement is designed to provide moderate sulfate resistance, making it suitable for construction projects like breakwaters, harbors, and jetties. Semen Merah Putih Ultramix-II is produced according to SNI 2049-1:2020 Type-II.
3. Portland Composite Cement
Portland Composite Cement includes a type called Semen Merah Putih Supermix, produced according to SNI 7046:2022. It is suitable for general construction that does not require specific conditions, such as sulfate resistance or low heat of hydration.
Additionally, Supermix's rheological characteristics are designed to facilitate easy pouring, resulting in optimal concrete density and compressive strength development. This cement is ideal for the ready-mix concrete industry, precast (u-ditch, concrete pipes, paving blocks, CLC, etc.), and mortar.
4. Hydraulic Cement
Hydraulic Cement is divided into two product types: Semen Merah Putih Flexiplus and Semen Merah Putih Primaplus. Below are the explanations for both products:
a. Semen Merah Putih Flexiplus
This Hydraulic Cement is produced according to SNI 8912:2020 and comes in three options: GU, MS, and HE. Semen Merah Putih Flexiplus offers flexibility in its use, tailored to different applications.
Type GU is suitable for general construction that does not require special conditions, like building bridges, roads, buildings, and other infrastructure. Type MS is used in applications that need moderate sulfate resistance, such as harbor construction, breakwaters, and jetties.
Type HE is used for applications requiring high early compressive strength, such as producing high-strength concrete in the precast industry, including piles, girders, and other products using both spun and non-spun processes.
b. Semen Merah Putih Primaplus
This Hydraulic Cement is produced according to SNI 8912:2020 and includes Portland cement clinker and GGBFS (Ground Granulated Blast Furnace Slag).
This combination is designed to improve durability against sulfate attacks and reduce the heat of hydration. It comes in two types, GU and MS, which have the same applications as the options in Semen Merah Putih Flexiplus.
5. Portland Slag Cement
The products included in Portland Slag Cement are Semen Merah Putih Durapro and Semen Merah Putih Ecopro. The explanations for both are as follows:
a. Semen Merah Putih Durapro
Produced according to SNI 8363:2017, this Portland Slag Cement is designed to provide moderate sulfate resistance. Semen Merah Putih Durapro is suitable for foundations in sulfate-containing soil and concrete exposed to seawater. It is also ideal for constructing industrial facilities exposed to sulfate environments.
b. Semen Merah Putih Ecopro
This Portland Slag Cement is an eco-friendly product with low carbon dioxide emissions and excellent resistance to sulfate attacks and carbonation in concrete. Produced according to SNI 8363:2017, this cement is designed to provide sulfate resistance and low heat of hydration.
Semen Merah Putih Ecopro ensures low hydration heat, making it ideal for building structures exposed to sulfate environments and mass concrete production, such as dams, raft foundations, and more.
Using Semen Merah Putih Ecopro also reduces the risk of carbonation in concrete. The low heat of hydration helps minimize stress caused by temperature accumulation during the hydration process in large-volume concrete.
