Stone Descriptions: Marble Marble is a metamorphosized sedimentary rock. Due to different crystallizations and impurities present over the millennia, marble comes in an infinite variety of color. For this reason, and given its preciousness, marble is generally used in construction for interior and exterior purposes. For similar reasons, we generally see this material in the form of slabs, and not as a structural building material. Marble is a relatively porous stone. This makes it easily…

The importance of concrete for mankind is so huge that hard to really appreciate so it is not surprising that people living today in concrete houses, driving on concrete roads don't have even an idea that they owe it to ancient Romans. Even that in case of arch they not discovered all by themselves We can be grateful for Romans that they not wasted legacies of earlier generations respected it and learned from them with Greek philosophy also secrets of architecture. I like to think…

Stabilize The Soil Before Building Your Parking Lot Sometimes, it's not possible to begin construction work until the soil has been stabilized. In order to put down a road or parking lot, the soil has to be compacted to hold the weight of the pavement without shifting. If you need to add a new parking lot but the soil isn't suitable because it is sandy, then soil stabilization might be able to help. Here's an overview of how it works. Stabilization Leaves The Soil In Place An alternative to…

The mixture requires adding water, additives and sand in the correct proportions if the sealant is to perform as it should. Although some people believe that sand is merely a filler that is added to reduce the amount of dry sealant needed, nothing could be further from the truth. Sand Provides Important Safety Features Sealcoating without…

CHAPTER-1 INTRODUCTION Concrete a manmade material widely and greatly used in construction Industry. This concrete is a mixture of adequate proportion of cement, water and aggregate. Hardening (or) strength of this material is obtained by the chemical action between water and cement. As the time increases the stronger it grows (i.e strength of concrete is directly proportion to its age).The durability, strength, versatility and other characteristics of concrete depends upon the properties and…

Fig. 6 shows the results of air permeability, total water absorption, and voids. R mortars had lower permeability than the mortars with WTS. Air permeability of R was 1.13 x 10-13 m², a value 5 times higher than L60. The air permeability increased with increasing WTS content. The water absorption values ranged from 10.6% to 13.7%, and the voids from 9.6% to 12%. The results show that WTS replacement increased the porosity and permeability of geopolymer mortars. The geopolymer binders with WTS…
