POLYMER COCNCRETE 1. Introduction Despite being thought of as a modern material‚ concrete has been in use for hundreds of years. The word concrete comes from the Latin concretus‚ which means “mixed together” or compounded. Concrete is an extremely popular structural material due to its low cost and easy fabrication. Concrete is made up of sand or stone‚ known as aggregate‚ combined with cement paste to bind it. Aggregate can be of various sizes. It is broadly categorized as fine (commonly

Chemistry in everyday life : Our entire universe is made up of matter which is constantly changing forms and evolving into other forms of energy. Chemistry is defined as the study or science of this ever changing matter. The other sciences which we study commonly like biology‚ physics and mathematics are all dependent on chemistry and are known as specific studies under the elaborate subject of chemistry. Since there is chemistry seen in biological forms as well as physical states of nature‚ there

Neutralising in everyday life In life we use the neutralising method a lot to help us in everyday tasks. Here are a few examples of neutralisation. Farming On farms the soil may sometimes become acidic. In these cases plants will not grow and they need to neutralise the soil for they’re farming. Limestone is commonly used for neutralising soil; it is a sedimentary rock that is commonly found in quarries. It is a compound consisting of calcium‚ carbon and oxygen called calcium carbonate (CaCO3)

But life is always somehow little bit complicated. Not only because life is not predictable: we do not know today what is going to happen in a year’s time or what is going to happen next year. But also because life has got its positive and its negative sides. Positive sides are that life is beautiful. It is full of surprises

Stress and everyday Life Everyone has used the word “stress” before‚ what is it‚ and why is it a commonality upon the population in the western world. The word stress is defined “Physical‚ mental‚ or emotional strain or tension”. 1 Has Selye‚ a pioneering endocrinologist‚ coined the original definition of the word stress‚ in the mid-twentieth century. 2 But why do we get stressed? It seems that the modern worlds business culture is the main feed for stress. The long hours working in a office‚ not

CONDUCTING POLYMERS By Colin Pratt INTRODUCTION Until about 30 years ago all carbon based polymers were rigidly regarded as insulators. The idea that plastics could be made to conduct electricity would have been considered to be absurd. Indeed‚ plastics have been extensively used by the electronics industry because of this very property. They were utilized as inactive packaging and insulating material. This very narrow perspective is rapidly changing as a new class of polymer known as intrinsically
