Quality Assurance

Six Main Quality Guarantees and Certifications

Taiwan Cement Corporation (TCC) is committed to quality and is dedicated to developing environmentally friendly products. TCC also enhances management mechanisms and establishes autonomous inspection systems.

Brand Cement: Cement products with carbon footprint labels certified by the Environmental Protection Administration of R.O.C.
Six raw material inspections: “cement, sand and gravel, slag, fly ash, chemicals, mixing water,” inspected by the TAF laboratories of TCC and SGS with qualification certificates.
Six third party certifications: Cement specimen compressive strength report, GRMC cement quality logo, ISO 9001, ISO 14001, ISO 45001, TCRI product traceability certification.

Best Guarantee, TCC Product Safety Policy

TCC values product quality. For ready-mixed concrete, the mix proportion design strength requirement is 500psi higher than the target strength, and the 28-day shipping strength is ≥ 1.10f'c (specified strength). Shipment mix proportion data and cement amount ≥ 50% cementious material are disclosed in order to provide safe products to customers.

Product Traceability

Outstanding Technologies, TCC TAF-Accredited Concrete Laboratory

To continue enhancing competitive advantages of our products, TCC invested over NT$100 million to build a TAF-certified concrete laboratory. In addition to providing testing of materials and products for all TCC RMC plants, the laboratory also provides training for quality assurance personnel to improve TCC product quality in the short run and also provide technical consultation and services regarding material design, quality and construction for domestic clients of major construction projects in the mid- and long-run.

A Pioneer in Promoting Product Tracing

To improve product quality transparency, TCC implemented a product traceability system in 2019. Clients who use TCC branded RMC can utilize this client relationship management system to check the details of TCC products including cement, sandstone, slag, fly ash, agents, and water. For each delivery of RMC, clients can use the system to obtain real-time information on product quality such as quality testing reports, quality assurance certifications, chloride ion testing, and compressive strength reports.

Trustworthy, Third-party Certification

The product traceability system has earned customer acclaim after its establishment. Content of the system is constantly upgraded and introduced digital governance tools as AI intelligent algorithms to offer quality variation analysis from 2021. Information regarding the changes of products in terms of strength is determined. TCC collaborates with Taiwan Construction Research Institute (TCRI) to conduct quality ratings of the contents of monthly raw materials and shipment from individual plants. Customers can thus access factual trends of concrete products changes. TCC also facilitates production quality control and increases the credibility of the system, demonstrating TCC’s rigor and confidence in the raw material controls and product quality.

Concrete Technique

Concrete Quality and Technology

To enhance building quality, maintain household safety, and reduce carbon footprint (CFT) of the construction process and applications, in addition to formulating concrete with high-quality TCC cement, we maintain a high-quality cement gradation design without cutting corners. Moreover, in response to market demand, we have successfully developed various concrete products, including self consolidated concrete (SCC), high-flowable concrete (HFC), and high performance concrete for specific construction needs. The well-known construction projects including Taipei 101 and Taiwan High-Speed Rail stations all use TCC concrete. On top of the excellent performance, these concrete products have effectively reduced energy consumption and enhance construction safety.

Types	Main Features
	Structures: Our unique gradation design maintains a balance among fillers (aggregates), water, and cementitious materials (cement, fly ash, and slag..etc). Optimal standard: Slump of 15-18 cm and compressive strength of 2,000-5,000 psi.
	Replace cement with other industrial byproducts - slags and fly ash, and use chemical admixtures with the best quality. SCC characteristics include high flowability and high formwork filling ability. As SCC casting itself by gravity without the need for compacting, this can reduce energy consumption and noise from the on-site construction equipment, improving the quality and safety of living. With sufficient consistency, SCC is able to resist segregation during construction. The uniformity of SCC is better than the conventional concrete as it brings an impressive improvement of overall quality and durability of reinforced concrete structures.
	Features include energy and noise reduction during construction. Apart from water-free workability and low slump loss and bleeding, HFC is characterized with high flowability, high water tightness, and high resistance to segregation. Therefore, it is the perfect solution for problems such as the need to add water when pumping, honeycombed concrete, bleeding, crust, shrinkage, and cracking, that are commonly found in conventional concrete. These excellent characteristics can reduce energy consumption and noise of on-site construction equipment.

Types	Main Features
	Special standard: 90-day design with compressive strength above 10,000 psi. Best technique: The application of concrete casting inside steel columns (CFT method) for the Taipei 101 improves Taiwan’s concrete manufacturing technique.
	Special technique and standard: Characterized by its bleeding free, shrinkage free, and high strength performance, the non-shrink concrete is suitable for steel structure foundations, foundation piles, bridge support pads, machine bases, bridge expansion joints, and repairs.
	Best technique: Superior to the regular concrete's water-tightness and permeability resistance characters. Best quality: Features including high flowability, high workability, low water consumption, small shrinkage and creep, and longer durability.
	The best technique and special standard: Tailor-made products based on customers' requests for specific construction needs.
