AQURON 300 - Additive for Concrete Waterproofing & Durability

AQURON 300 additive reduces shrinkage and slabcurl to a minimum, while improving density, anti-dusting, and surface hardness. Cement particles are more effectively “saturated” by the AQURON 300 mix water and this subsequently increases the quantity of hydration products per cement particle, optimising achieved strengths, and contributing to a significant drying shrinkage compensation

Concrete eggs in winemaking : WineWisdom

Concrete has been used successfully since the 19 th century for winemaking, but the egg shape is new. Regardless of shape, evaporation loss is quite small, as is temperature fluctuation, though the concrete is liable to crack if temperatures get too high. A critical thing is a continuous flow of liquid in the egg vat.

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, lime based cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual
