strengthen the exchange of concrete experience and knowledge of community-based risk reduction. Practical, simple steps like this publication, which shares clear, useful examples on how to decrease disaster risk at the grassroots, are vital to strengthening the disaster resilience of not only houses, but entire communities and nations.

Surveying is a very important part of Civil Engineering.It is a basic course for all universities for civil engineers. Here in we have gathered some pdf lectures on surveying. We hope students all over the world will find it helpful.

to aid the use of slings or forks. Suitable means should be used to protect workers from injury due to sharp corners, projections or edges on structures and/or stored material. Corners of stored material should be clearly marked. Safe access, by means of ladders, platforms or walkways, must be provided for workers required to climb or remove goods

Grinding concrete floors is preferred over the use of filling compounds. If filling/leveling compounds are used, they must be Portland Cement based and have a compressive strength equal to or greater that 3000 psi when cured. Use of Titebond 821 Premium over light weight concrete and all gypsum based materials requires the use

the industrial grinding of cement, even without the use of grinding aids. Therefore it can be assumed that the surfaces of the majority of commercial clinkers are predominantly or even completely hy - droxylated. This is also important because it as-sists the grinding, in other words water is a weak grinding aid. The chemical reaction of oxide ions

costs for cement, it is very important to optimise the existing grinding installations. Experience has shown that the potential for optimisation is greatest in the cement grinding process in a cement plant The benefits that can be achieved due to the optimisation of cement grinding system through process diagnostic study are:

Looking first at cement based grouts, these materials are essentially fine concretes - cement, aggregate and admixtures in a bag - to which we add water on site. Concrete shrinks - so does a cement based grout. What we need to do is minimise or compensate for this shrinkage, hence the term "Shrinkage Compensation".
