In this study, the effect of polycarboxylate ether-based water reducing admixture (WRA) main chain length on fresh state properties, compressive strength, ultrasonic pulse
The PCE superplasticizer replaced both the PNS/lignin and Type A water-reducing products at about one-third the dosage rate. Also, note the 50% drop in AEA dosage rate with
Polycarboxylate-based water reducing admixtures (PCE) are widely used in concrete technology as they have superior properties such as ease of molecular structure
These (HRWRAs) increase the workability of a fresh concrete mix by dispersing flocculated cement particles which entrap free water molecules within the concrete system.
Polycarboxylate-based water reducing admixtures (PCE) are widely used in concrete technology as they have superior properties such as ease of molecular structure
The use of PCEs, especially PCE-5C, can effectively reduce the total drying shrinkage of cement-based materials. Abstract. This study investigated the impact of five
With this in mind, this article will focus on the impact of admixtures on power consumption during concrete mixing, thereby reducing energy consumption in concrete production in ready-mixed
Polycarboxylate-based (PCE) superplasticizeris a kind of concrete admixture with high water reduction rate and low slump loss. It can greatly increase the rheological properties of fresh
Sika ViscoCrete-2199 is a high range water reducing admixture based on selected PCE polymers for promoting high ultimate and early strengths in both ready-mix and precast concrete. Sika ViscoCrete-2199 is chloride free according to BS 5075 and is compatible with all types of Portland Cement including Sulphate Resistant Cement
Produc ALPHALITH superplasticizer FT 30 LV (FM) is a highly concentrated, very effective superplasticizer with purely synthetic active ingredients for the economical production of high quality concrete and high performance concrete in the precast or ready-mix plant and on
RA mixed with fresh water TWW mixed with normal aggregates Workability Slump values of recycled aggregate concrete (RAC) decrease with increasing percentage replacement of RA [11,14,29,46,47] TWW
Concrete plants accumulate large amounts of concrete wash water. This water, which pH is highly alkaline, has a negative impact on the environment. Its reuse in fresh concrete slightly reduces its mechanical properties. The combination of concrete wash water and zeolitic by-product led to an increase of 4.6% in the compressive strength at 7 days hydration and up
It has been calculated that a 9-m 3 ready-mixed concrete truck contains, at the end of each working day, approximay 200–400 kg of returned plastic concrete [1], [2]: this material can be left overnight in the truck with the addition of hydration control admixtures [3], [4] or washed out. When washed out, with the addition of about 700–1300 l of water, the material can
This study was motivated by the necessity to recycle sludge water resulting from washing out concrete mixing trucks - a problem of both environmental and economic importance for the ready-mixed

The Using of Concrete Wash Water from Ready Mixed Concrete Plants in Cement Systems In this way, the consumption of tap water is possible to reduce in cement systems. Keywords: concrete wash
l Can be mixing with water, or can be added into the concrete batching plant separay. l Can be mixed with high plastic retention type polycarboxylate superplasticizr and all kinds of retarders. Examples of ELT-WR30: Product in an ready-mixed concrete mixing station, the proportion and performance of concrete are showed in following
