Dry-Mix & Pre-Blended Products
A pre-blended product is only as consistent as its sand. Manufacturers need it dry, sized to their formulation, and the same in every load.
Our product: Kiln-Dried Sand
MRP sand for dry-mix manufacturers
MRP supplies kiln-dried sand to dry-mix and pre-blend manufacturers, sized to their formulation. Dry-mix mortars, renders, grouts, repair mortars, self-levelling compounds and bagged shotcrete are made to a formulation: cement, sand and additives blended in set proportions and bagged. Two things about the sand decide whether the product works. Moisture — any water in the sand starts setting off the cement in the bag and changes the mix on site. Grain size — the grading sets the workability, strength and finish, so it has to match the formulation every time.
Why we kiln-dry it
Drying does two things. It brings the sand to a known, low moisture content so it can be blended and stored. And it makes accurate screening possible, because moist sand clumps and blocks a screen while dry sand separates cleanly. A manufacturer can specify a fraction or a grading curve and get it, not an approximation.
The MRP product
Kiln-Dried Sand from MRP Sand Quarry: washed to remove silt and clay, dried in our own kiln, and screened to a fraction between 0.3 mm and 6 mm — a single close size, a band between two sieves, or a grading to the customer's curve. Made on site at Talgai, Queensland, so the same sand comes off the same plant for every order.
Supply
Bulk supply to manufacturers and blending plants across Queensland. Send the target grading or sieve band, the moisture limit if there is one, the tonnage and the delivery point.
