1. Introduction. Over the last century, Portland cement-based concrete has become the highest manufactured product on Earth in terms of volume. Concrete is used worldwide as a building material and is the most consumed substance on Earth after water (Sakai, 2009).The volume of concrete produced globally is approximately 5.30 billion m 3 per year (Roskos et al., 2011), with more than …
The standard Bogue calculation refers to cement clinker, rather than cement, but it can be adjusted for use with cement. Although the result is only approximate, the calculation is an extremely useful and widely-used calculation in the cement industry. The calculation assumes that the four main clinker minerals are pure minerals with compositions:
Since the porosity of the dross and the cement paste is not the same, the air is entrapped in the mixed cement paste, resulting in improved compressive strength. Reddy et al. (2014) replaced the cement in concrete by 5, 10, 15, 20, and 30% wt.% of aluminum dross. Then, they measured the 3-, 7-, and 28-day compressive strength of concrete specimens.

Cross laminated timber (CLT) panels are formed by stacking and gluing together successive perpendicular layers of wood. The layered stacks are then pressed in large hydraulic or vacuum presses to form an interlocked panel. The panel is then sized and shaped with a Computer Numerically Control (CNC) machine into a fully construction-ready component.
