Continental Cement

Continental Cement is a very good supplier that treats us right with a sales staff that is always friendly and helpful. Their terminal and plant are very clean and safe; they load our trucks quickly so we can get back on the road. Continental always has the material when we need it, and I like their cement as well any product that I've ever used.

Alternative building materials for green construction

Using wood as a material in building construction can have significant environmental benefits. Manufacturing wood for construction is less energy intensive than other materials, including concrete, steel, cement or glass production with some percentage of recycled material. The finished product also has lower embodied energy. Rammed Earth

Why Alkali-Activated Materials are NOT Geopolymers

Jul 27, 2017 · To sum-up Alkali-Activated Materials (AAM) are NOT Polymers, so they cannot be called Geo-Polymers. Geopolymers are NOT a subset of AAM because they are not a calcium hydrate alternative (no NASH, no KASH). They belong to two very different and separate chemistry systems (a hydrate/precipitate that is a monomer or a dimer versus a true polymer).

What is the water-cement ratio? Quora

Concrete hardens as a result of the chemical reaction between cement and water (known as hydration, this produces heat and is called the heat of hydration). For every kilogram of weight of cement, about 0.35 lit. of water is needed to fully complete hydration reactions. However, a mix with a ratio of 0.3

Cement and Concrete An Overview

Jul 24, 2018 · Lime is made by burning, or calcining, limestone—and that's how limestone gets its name. Chemically, lime is calcium oxide (CaO) and is made by roasting calcite (CaCO 3) to drive off carbon dioxide (CO 2 ). That CO 2, a greenhouse gas, is produced in great quantities by the cement industry.
