Generally, There are 5 types of Mineral admixtures used in concrete are mentioned below:
-The effect of GGBS, Metakaolin and Fly ash on concrete is on setting time of high strength concrete.
-All the minerals can reduce bleeding in concrete.
-The heat of hydration increased due to chemically active minerals (Metakaolin and Silica fume)

For pretension concrete the steel is the first tensioned in a frame or between anchorages external to the member, therefore the concrete is then cast around it. Post tensioned concrete is made by casting concrete that contains ducts through which tendons can be threaded.

Fly ash bricks can be used in place of ordinary building stones and bricks which is a good one but the main defect is that fly ash bricks are regional.

Generally hill profiles are irregular. So, the most efficient method for hill road is the prismoidal method (Simpson method). It based on the assumption that profile is parabolic between two sections. For use of this method, it is necessary that profile should be divided into odd number of section.Read more

For use of this method, it is necessary that profile should be divided into odd number of section. If the profile is divided in even number of section than apply prismoidal method till the second last section and apply the trapezoidal method in last section.

the criteria for choosing type of estimate in any building construction are given below. 1.What phase is the project in?

the criteria for choosing type of estimate in any building construction are given below.
1.What phase is the project in?
Perhaps the most important, or at least first, determining factor for selecting the estimating method, or approach, is the project phase. Where is the project in it’s life-cycle? If it is in the conceptual design phase you might consider using the Universal Factors method. This method, in it’s simplest form, works as a type of “analogy” estimating approach. If you have similar past projects in your “bottom right-hand drawer” then you may be set. Otherwise, you may need to use a Universal Factors model.
2.What project data is available?
As they say “data is king”. That statement certainly holds true for estimating. Not only the volume, but the type of data available to you, can make all the difference in the method and accuracy of your estimate. Review the data available to you (technical or unit cost). The amount of data on hand can help you decide which method you will use, the cost drivers, and many more aspects of your estimate.
3.What is the purpose of the estimate?
You should always keep in mind the purpose of the estimate you are developing. Is your estimate attached to a detailed bid or proposal for a potential client or is it going to be used to “cost out” one of multiple approaches to a solution for management review? If the latter, perhaps all you need is a Rough Order of Magnitude (ROM) estimate? The estimates purpose (read: audience) determines the approach you take and what attributes of your estimate you include or highlight.
4.What is your time-frame?
When you have the time (and data points), it is often best practice to develop as detailed an estimate as possible. This is especially true when estimating construction or preparing a T&M bid or proposal.
5.What estimating tools are available?
After all is said and done, it may come down to the tools you have in your toolbox. Most estimators, and I know I am in this category, are Excel aficionados. You can often find me buried in a spreadsheet somewhere. If I am pulling together a “back-of-the-envelope” estimate I will often use Excel. However, Excel has it’s limits. There are multiple tools on the market for QTO estimating that provide management capabilities over and above what Excel can offer.
What is out-turn work in quantity surveying?
The capacity of doing work by an artisan or skilled labour in the form of quantity of work per day is known as the task work or out turn of the labour. The out-turn of work per artisan varies to some extent according to the nature, size, height, situation, location, etc., In bigger cities where specRead more
The capacity of doing work by an artisan or skilled labour in the form of quantity of work per day is known as the task work or out turn of the labour.
The out-turn of work per artisan varies to some extent according to the nature, size, height, situation, location, etc., In bigger cities where specialized and experienced labour is available the out-turn is greater than small towns and country sides. In well organized work less labour is required.
