How to Improve the Concrete Pumping Performance of High Related Information

Underwater Concrete - an overview | ScienceDirect Topics

A.K. Al-Tamimi, in Developments in the Formulation and Reinforcement of Concrete, 2008 6.1 Introduction. Underwater concrete "UWC" is one special type of high performance concrete used in the past, present, and in the foreseeable future as long as there is need to construct bridges, with foundations in soil with high water levels, and almost all off- and on-shore structures.

Concrete Admixtures - Sika

Chemical Admixtures Are One of the Components in High Performance Concrete. The first step in optimizing concrete is to recognize that concrete is no longer simply cementitious materials, aggregates and water. It is a high performance material with not just four, but seven essentials – consisting of water, cementitious material, sand, gravel

Effect of Sand Fines and Water/Cement Ratio on Concrete

batched for concrete mixing (Table 1). Different batches of concrete consisting sand with fines content of 2%, 4%, 6%, 8%, 10% and 12% with three constant water/cement ratios of 0.55, 0.60 and 0.70 were prepared for the study. The amounts of coarse aggregate used were kept constant for all batches. The concrete were mixed using 1m3 drum

Pump cavitation and how to avoid it

pumping system is insufficiently planned and designed, it may lead to cavitation and its problems: noise and vibration, material damage, reduced performance and even pump failure. This white paper explains how cavitation occurs. It is intended to serve as a reference in selecting correct pumps, planning pump …

Major Problems in Concrete Pumping Works: How to Avoid

Certification | American Concrete Pumping Association

Certification has been shown to improve safety, decrease accident rates in the workplace, and has become a critical standard for customers looking for reliable, high-quality pumping contractors. Recertification keeps operators focused on correct practices and complete safety procedures.

Effect of W/C Ratio on Durability and Porosity in Cement

Water is often added to concrete placing for easy workability and finishability in construction site. The additional mixing water can help easy mixing and workability but causes increased porosity, which yields degradation of durability and structural performances. In this paper, cement mortar samples with 0.45 of W/C (water to cement) ratio are prepared for control case and durability

Sustainable Concrete Construction - Methods and Practices

Diesel fuel is used to transport concrete that release 0.009t CO2-e/m 3 empty returned journey is included. Onsite activities like pumping, vibrating, and finishing employed fuel is (1.5 L/m 3 pumped concrete), sometime concrete is craned instead of pumped so (2x1.5 L/m 3) to take other type of pumping into consideration and it emits 0.009t CO2

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.
