As a water reducing agent, sodium gluconate for concrete can make concrete mixes have better processability and increase concrete slump.By adjusting the water-cement ratio and adding sodium gluconate, the strength of the concrete structure can be enhanced. Besides, the cement content can be reduced while maintaining the original strength of the concrete.
Our company will continue to focus on the R&D and manufacturing of Borida PCE 50 Water Reducing, Silica Fume 92, Polycarboxylate Superplasticizer for Construction, and strive to become a high-quality supplier in the industry.We have strengthened the management of the enterprise and the quality of our concrete admixture formulation book has been …

High-Range Water Reducing Admixture (HRWRA) is indispensable in modern concrete to enhance flowability at relatively low w/c ratio. It has been an essential component in high performance, self-consolidating, fiber reinforced concrete, and more. ... The cement powder was slowly added to 90% of the water and mixed at a speed of …
admixture formulations to be used for cold weather concreting and then to down select ... concreting is focused on the development of an antifreeze admixture formulation for the placement of concrete at low temperatures in accordance with the specifications of ACI 306-02. Admixtures such as Pozzutec 20+ have been tested individually as possible
With an admixture, the crystalline powder is added to the concrete as it is being mixed, prior to the pour for new construction. ... Their formulation is chemically different than others, but it does basically the same thing — KIM chemically reacts with water and unhydrated cement particles to form insoluble needle-shaped crystals that fill ...

To test the effect of EADF as an admixture, several conventional concrete samples were prepared by replacing 0% (control), 2%, 5% and 8% of cement with each EAFD group.
For over one hundred years, Sika has been producing high quality, innovative admixture technologies for concrete. Sika's first product, appropriately named Sika® …
In one embodiment, the admixture formulation contains at least one polyphosphate, such as sodium polyphosphate or potassium polyphosphate. Without wishing to be limited by theory, the inventors believe that the polyphosphate acts as an active cement dispersant for promoting the dispersion of cement particles.
Since the publication of the first edition ten years ago, significant developments have occurred in the use of admixtures in concrete. Eight new chapters and a full update of the preceding ten chapters bring this book up to date; reflecting the relative advances made in the science and technology of different groups of admixtures. The …
Air Entraining Concrete Admixture Air entraining admixtures are one of the most important inventions in concrete technology. Their primary function is to increase the durability of concrete under freezing and thawing conditions. When added to concrete mix, these admixtures will form millions of non-coalescing air bubbles throughout the mix and ...
