This high-tech product was developed through prolonged and arduous efforts by our company’s technical team, building upon an invention patent held by the Tianjin Cement Industry Design Institute and receiving strong support and guidance from the Institute and leading industry experts. It integrates the superior properties of sulfoaluminate cements and a variety of cementitious materials, achieving well-balanced performance across early, mid, and late stages of curing. After hydration, the resulting products exhibit a highly dense microstructure, low drying shrinkage, slight expansion, rapid setting and hardening, high early strength, and sustained strength gain with age. Consequently, it is ideally suited for applications such as floor screeds, high-strength repair mortars, high-strength non-shrink grouts, grouting materials, and ultra-high-performance concrete (UHPC) products.

Technical Features

Physical Properties

◆Specific surface area: greater than 400 m² ²/kg

◆ Setting time: Initial set 8–20 min, final set 15–40 min

◆Strength:

◆This product exhibits a low drying shrinkage rate and minimal volumetric change; the cement-based self-leveling mortar prepared using this cementitious material has a volumetric change of 0.0079%–0.01%, which is only 10%–12.5% of that observed in products made from silicate cementitious materials.

◆ Excellent workability: Good workability when combined with mineral admixtures, resulting in low curing difficulty and reduced curing costs.

◆ Exhibits excellent impermeability and superior resistance to sulfate attack.

◆Free expansion rate: at a cement-to-sand ratio of 1:0.5, the 28-day free expansion rate is 0.00% to 0.15%.

Scope of Application

Currently, the primary application areas for this product include self-leveling mortars, sculpted mortars, terrazzo mortars, high-strength repair materials, high-strength non-shrink grouting materials, grouting reinforcement materials, waterproofing and leak-stopping materials, as well as GRC and UHPC products.

◆Flooring mortars, such as cement-based self-leveling mortars. These can effectively address issues such as dimensional changes in cement-based self-leveling mortars and their bond strength with the underlying concrete substrate.

◆For terrazzo and sculpted mortars, belite sulphoaluminate cementitious admixtures offer advantages such as early strength development, rapid hardening, low shrinkage, and corrosion resistance, thereby effectively addressing the shrinkage issues associated with terrazzo applications and the challenges of achieving early strength and corrosion resistance in sculpted mortar applications.

◆Airport runway and highway rapid-repair mortar can achieve normal service performance within two hours. Road concrete formulated with belite sulphoaluminate cementitious material blended with an early-strength admixture requires no special curing. Moreover, this cementitious material exhibits strong bonding, high fluidity, rapid setting, and slight expansion, effectively mitigating concrete shrinkage; its superior impermeability also prevents surface water from infiltrating and damaging the road base. Consequently, it is an ideal matrix material for emergency road repairs, grouting reinforcement, wind-turbine foundation grouting, bridge bearing grouting, and other similar applications.

◆It can meet the requirements for rapid setting and high early strength in other civil engineering applications. Due to its outstanding properties—such as high early strength, excellent resistance to permeation, good freeze–thaw durability, superior long-term stability, corrosion resistance, short setting time, low alkalinity, and low free expansion rate—belite sulphoaluminate cementitious materials are widely used in specialized engineering fields.

Instructions for Use and Precautions:

◆ During the formulation process, the product must be used only after verification against the factory’s quality test report or following re-testing.

Packaging and Storage

◆ Store in a sealed container in a dry environment; shelf life is no less than 45 days. Use immediately after opening; if the product expires or becomes damp, its performance may be compromised and it must be retested and found compliant before use.
