Concrete and Mortar Admixtures: A New Method for Superplasticizing Materials with High Content of Porosity
Abstract:
The application of concrete and mortar admixtures in the construction industry has become increasingly important due to their high ability to provide excellent strength, durability, and aesthetics. However, this process often results in a higher percentage of porosity, which can lead to the formation of microdiffuse structures that reduce the amount of consolidation and may also affect the overall performance of the material.
A new method called solid-mortar admixtures (SMS) was developed by researchers who have successfully employed it in the construction of high-porous concrete mixtures. SMS is a combination of concrete admixtures and a water-soluble material that allows for efficient mixing and dissolving, leading to a higher concentration of porosity and improved bonding between the cement and aggregates.
The SMS method uses a variety of operating parameters such as the temperature, pressure, and initial concentration of the cement and aggregates. The developers tested different combinations of these parameters and found that the SMS method could achieve an average porosity of 40-50% when applied to high-porous concrete mixtures.
In addition to its superior porosity, SMS also offers other benefits such as improved adhesion and contact resistance. By reducing the amount of consolidation during the mixing process, SMS can improve the overall strength and stability of the mixture.
Keywords: Concrete admixtures, mortar, SMS, high-porous concrete, porosity, bonding, adhesion.

5 FAQs about concrete and mortar admixture polycarboxylate superplasticizer liquid solid content 50%
Q: Does concrete and mortar admixture polycarboxylate superplasticizer liquid solid content 50% affect the color of concrete?
Answer: Normally, polycarboxylate superplasticizer will not change the natural color of concrete.
Q: What is the recommended dosage of concrete and mortar admixture polycarboxylate superplasticizer liquid solid content 50%?
Answer: The addition amount is generally 0.15% to 0.4% of the cement weight, which is adjusted according to the concrete mix ratio and performance requirements.
Q: Can using concrete and mortar admixture polycarboxylate superplasticizer liquid solid content 50% extend the setting time of concrete?
Answer: Some polycarboxylate superplasticizers contain retardant components, which can moderately adjust the setting time, but not all products have this effect.
Q: Is concrete and mortar admixture polycarboxylate superplasticizer liquid solid content 50% suitable for all types of cement?
Answer: concrete and mortar admixture polycarboxylate superplasticizer liquid solid content 50% has a wide range of cement adaptability, but different cements may need to adjust the type or amount of superplasticizer to achieve the best effect.
Q: Does concrete and mortar admixture polycarboxylate superplasticizer liquid solid content 50% have any effect on the shrinkage of concrete?
Answer: Appropriate use usually does not significantly increase the shrinkage of concrete, but excessive water reduction may slightly increase drying shrinkage. Pay attention to the balance of the formula.
