What Is Meant By 'Concrete Slump' & Why Does It Matter

A concrete slump test is a way of finding out the consistency of different concretes. The benefits of performing a slump test are that it shows the workability of the concrete and the ease with which it flows, as well as being an indicator of an improperly mixed batch. Checkout our guide on Concrete Slump Tests – a detailed guide on how to

Chapter 16 Design of Pumping Stations

Pumping stations can be grouped as follows: - pumping water from a water source such as a river; - for lifting water (high quantity, low pressure) from a well; - for pumping water into a supply system, elevated water tank or water tower; - to increase pressure. Pumping stations for the first two functions are generally of 2-20 m lifting capacity.

Chemical Admixtures - Portland Cement Association

Superplasticizers, also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete. Flowing concrete is a highly fluid but workable concrete that can be placed with little or no vibration or

Improving Performance With KPIs and Performance Measures

Improving Performance With KPIs How to use KPIs and performance measures to improve organisational or business performance. Putting your performance measures or KPIs to use is how you get the return on all that invested time and money associated with choosing them, implementing them and reporting them.

an increase in aggregate size. High-strength concrete containing basalt and normal­ strength concrete containing limestone yield higher fracture energies with higher coarse aggregate content than with lower coarse aggregate contents. The fracture energy of high-strength concrete containing limestone and normal-strength concrete

Positive Displacement Pump Basics

Apr 14, 2015 · A positive displacement pump uses a variety of rotating or reciprocating parts to move fluid into an enclosed volume. When enough pressure is built up in the chamber, the pump moves the liquid out and into the discharge system. Given the versatility of this pump, it is used in a variety of industries and has many applications.

entrainment will dramatically improve the durability of concrete exposed to cycles of freezing and thawing (Fig. 6-2). Entrained air greatly improves concrete's resistance to surface scaling caused by chemical deicers (Fig. 6-3). Fur-thermore, the workability of fresh concrete is improved significantly, and segregation and bleeding are reduced or

Pump and piping sizing

The pump and the tube size or diameter are the 2 elements that typically can be changed. The bigger the pipe the easier it is to increase the flow rate within reason. It will not help you to go from a ½ in dia. tube to a 3 in pipe. Or maybe it would if you have completely mis-estimated the size of tube required.
