October competition winner P. Baggs – announced 19th October 2011 Question: Floor screeding sometimes needs a little bit of creativity! Take a look at this picture. Tell us where and how many screed pumps are on this project, you must also tell us the locations. Clue: the answer is not 2. Answer: 3 Count and follow the pipes. And you...
A flat concrete substrate is one of the most important pre-requisites for the application of unbonded screeds or floating screeds. The purpose of keeping a screed unbounded is to allow the screed to slip on a polythene membrane, providing a suitable screed construction for depths of over 50mm. Taking into consideration the fact that the screed will...
If you thought rolling up the screed pipes is no rocket science, we agree with you. But, it is often the seemingly obvious steps that tend to be taken for granted- and ultimately omitted. Believe us; following these simple steps will make the whole process of transporting the screed pump a lot easier and...
A blockage in the mixing vessel of screed pumps will become evident when the pressure builds up on the pressure gauge and the screed pipe stops moving. Here are a few tips on how to locate and clear the blockage in the mixing vessel. The easy way to locate the blockage is to walk upon...
Blockages in the screed pipes is a common issue that has to be dealt with while using a screed pump. Though the entire procedure of clearing the blockage is quite simple, it is important to follow the safety precautions to carry out the procedure safely. We have here a few tips on how to locate...
The quality of a screed is highly reliant on the method of mixing of the screed. Force action mixing of screeds using screed pumps is proven to yield screed mixes that are clearly superior in quality and homogeneity as compared to the usual screed mixes produced using free fall mixers. Given below are the steps...
Emergency stop procedure Hit emergency stop button or switch off the screed pump engine. Disengage blades. Release air pressure to stop any flow of screed. Switch pump to neutral.
Be it manual work or the use of machinery, it is always ideal to follow a set procedure to ensure higher productivity and improved efficiency. Given below is the standard procedure followed at CSC for ensuring the safe and efficient use of the screed pump: Visually inspect the screed pump for obvious faults. Check the engine...
Screed reinforcement is a common practice adopted to improve the strength of screed constructions, curb shrinkage and cracking and impart better impact resistance to screeds. It is the inherent nature of screeds to shrink and curl and develop micro cracks during the process of drying. Reinforcement of the screeds using wire mesh or fibres...
You might frequently see tips on how to protect a screed. But as they constantly go ignored- adding to the number of screed failures, we thought it would be more worthwhile to give a few tips on how to cause a quick screed failure easily. Here are 5 sure shot tips for guaranteed screed...
