Sulfur concrete is usually a Distinctive concrete that works by using sulfur to be a binder ห้างหุ้นส่วนจำกัดสหคอนกรีตอัดแรง and doesn't need cement or h2o.

Large-circulation concrete, like self-consolidating concrete, is analyzed by other move-measuring techniques. A single of those approaches features inserting the cone over the slender end and observing how the combination flows in the cone though it's steadily lifted.

Accelerating admixture-accelerators are additional to concrete to scale back environment time from the concrete also site to accelerate early toughness.
