Executive Summary Concrete is the most heavily used construction material in the modern world‚ and given the current global trends towards sustainability there is a need for significant advances‚ particularly in the construction sector. Geopolymer concrete (GPC) is a recent development in construction materials demonstrating similar structural properties to that of Ordinary Portland Cement (OPC) based concrete‚ yet whilst at the same time addressing the environmental footprint of the industry and

Investigate the Effect of Acid Rain on Building Materials Question: What is the effect of 6M sulfuric acid (H2SO4) on the corrosion rate of the 3 grams of steel as the amount (number of sprays) of sulfuric acid increases? Variables: Independent variable: the number of sprays of 6M sulfuric acid (0‚ 5‚ 10‚ 15‚ 20‚ 25 times) to observe its effect on the corrosion rate. Each spray will contain about 10mL. Dependent variable: The corrosion rate. It will be calculated by measuring the mass of steel

The purpose of this chapter 1‚ "The Material and Trading Worlds‚ circa 1400‚" is to describe what the world was like around 1400 in general terms. The author‚ Robert Marks‚ argues that most changes in history are the result of "huge processes that are hardly detectable‚" coming from the changes in social‚ economic‚ political‚ and cultural structures. He analyzes two major structural aspects of the world in the 1400’s: first‚ material and natural conditions under which most people lived; and second

Introduction The purpose of this laboratory was to first test the effect that increasing water content would have on the workability of fresh concrete‚ completed by way of a slump test. The second part of the laboratory was to check what the influence of a superplasticiser would have on workability of fresh concrete‚ this was completed by completion of a Vebe test

Is PVC an acceptable vent material for flue gases? Installing a new water heater or furnace can be tricky for the novice HVAC technician. There are many checks that need to be done and codes that need to be followed. While not being complete with the internals can lead to a harmful situation‚ one of the most important decisions that you will have to make is what material you should make the flue out of. Most furnace flues are made out of a metal material which is a proper decision do the high
