Six Steps to Develop an Effective Problem

Nov 01, 2017Here are six steps to an effective problem-solving process: Identify the issues. The first phase of problem-solving requires thought and analysis. Problem identification may sound clear, but it actually can be a difficult task. So you should spend some time to define the problem and know people's different views on the issue. Get price

How to Pour Concrete: 12 Steps (with Pictures)

2. Shrink-mixed concrete is mixed partially in a sta-tionary mixer and completed in a truck mixer. 3. Truck-mixed concrete is mixed completely in a truck mixer (Fig. 10-6). ASTM C 94 (AASHTO M 157) notes that when a truck mixer is used for complete mixing, 70 to 100 revolutions of the drum or blades at the rate of rotation designated by Get price

How Concreting Is Done Underwater By Tremie Method

This process of filling and discharging of concreting is repeated, without any interruption, until the concrete level comes above the water table. NOTES. 1- Pumping of water should not be allowed while concreting, because it may absorb cement particles from the concrete. Get price

How to Kill a Process from the Command Line

May 15, 2018Killing the process. Now we come to the task of killing the process. We have two pieces of information that will help us kill the errant process: Process name. Process ID. Which you use will determine the command used for termination. There are two commands used to kill a process: kill – Kill a process by ID. killall – Kill a process by name Get price

Concrete Driveway Construction

Curing of the concrete is the final step of the process, and one of the most important. Unfortunately, it's also one of the most neglected. In extreme cases, failure to cure the concrete immediately after final finishing can result in strength reductions of up to 50% by reducing the concrete's resistance to the effects of weather and increasing Get price

Design methodology for building projects

An iterative process . At its most basic level, design can be seen as an iterative process, where, at each iteration, there are inputs, there is a design process and then there are outputs. At the end of each iteration, the outputs are reviewed and then the process begins again. Iterations take place at a number of different levels: Get price

Under Water Concreting

The concrete undergoes a chemical change as it hardens and this produces a lot of heat. Sometimes, if the mass of concrete is very large, pipes carrying refrigerant coolant are used in the mass to assist the setting process to prevent the concrete from cracking. Q-21: Short note 1.
