The interdependence of the various parameters which influence the explosion pressure is described by the equation of state for ideal gases: P = n R T V where P is the pressure, V the volume, R the universal gas constant, n the number of moles of gas and T is the temperature. Other factors being equal, the increase of T due to the heat developed …

For example, a large cement factory in Ras al-Khaimah in the United Arab Emirates burns camel dung to power cement ovens. Another way to reduce emissions is to heat CaCO 3 using renewable sources—and such a process is what Massachusetts Institute of Technology (MIT) researchers investigated in a recent paper.

With cement contributing to a significant portion of concrete's environmental impact, a common specification strategy is to reduce the cement content of a mix design to the lowest possible level. Contrary to the strategy above, high-percentage cement mix designs can be a solution for a lower carbon footprint in some applications.

1) Dust is a common problem when working with a new kind of material, in our case, drywall. To minimize the amount of dust in your basement, always spray water on the drywall before using a sander or drill. This can reduce the amount of dust that will fly into your face and lungs by up to 85%! 2) Another common dust-producing tool is a grinder.
