Dry admixtures are added with cement and sand before mixing water, helping uniformity. Wet admixtures are added with mixing water to control workability and setting. Choose based on required water ratio and job type, especially large projects in Riyadh and Jeddah.
Properly dosed, certified Matkel admixtures do not reduce strength; they improve workability and reduce mixing water, supporting durability and crack resistance. Some options offer added sulfate protection, making them suitable for coastal works in Jeddah and Dammam.
Dosage depends on the admixture type and manufacturer, usually between 0.5% and 3% of cement weight, measured in milliliters or liters by concentration. Confirm the exact rate for your Matkel product while considering project temperature, water content, and target strength.
Yes. Approved, quality-compliant admixtures are available for white cement and ordinary Portland cement. Check Saudi specification certificates before purchase, especially for residential projects in Mecca, Medina, and Qassim where color consistency, finish quality, and durability are important.
First identify the goal: improving workability, reducing water, or accelerating setting. In hot areas such as Tabuk and Hail, select heat-tolerant admixtures that limit rapid evaporation and control working time. Request a sample and trial mix before buying large quantities to avoid cracking or quality loss.
