Influence of phosphogypsum purification with lime on the
For the analysis of the interaction of cements with water-reducing admixtures, a polyfunctional lignosulfonate-based plasticizer admixture, commonly used in the concrete industry, was used. The plasticizer presents, at 25 °C, pH of 5.74, density equal to 1.2092 g/cm 3, and solids content of 43.26%.
15 Types of Admixtures Used in Concrete - The Constructor
Normal plasticizer reduces the water demand up to 10%, mid-range plasticizers reduce the water demand up to 15% while super plasticizers reduce the water demand up to 30%. Calcium, sodium and ammonium lignosulphonates are commonly used plasticizers.

- When were plasticizer admixtures invented?
- The first plasticizer admixtures, developed in Japan in the 1960s , were introduced to the Brazilian market in the same decade . Initially, they were mostly adopted by consumers with a high-level technical background, such as concrete plants.
- Are chemical admixtures sold in Brazil?
- The National Union of the Cement Industry (SNIC) itself only published annual reports from 2001 to 2013. No national statistics were found on the sale or use of chemical admixtures. In this scenario, this work sought to contribute to the creation of a literary collection about Portland cement and chemical admixtures in Brazil.
- Are there standard admixtures for cement based composites in Brazil?
- In Brazil, there are no standards for admixtures for cement-based composites other than concrete (e.g., mortars and grouts). Table 7 shows the different types of standardised admixtures in the country and their equivalents in the US and UK.
- What type of cement is used in Brazil?
- The Portland Blast-Furnace slag cement (now CP III) was the first standardized cement with admixtures in Brazil (1966). It is equivalent to BSI type CEM III and ASTM binary blended cement type IS (“S” for slag), although the Brazilian type currently allows up to 10% limestone filler (which is not covered in BSI and ASTM binary blended cements).
- Can limestone filler be added to Brazilian cement?
- Due to these technical advantages and its relatively low cost, the maximum allowed addition of limestone filler in Brazilian cement has been increased over the decades. High Early Strength Portland cement (CP V) was first regulated in 1940, only 3 years after CP I.
- How many tons of cement are produced in Brazil?
- In 2019, according to the National Union of the Cement Industry (SNIC), the production of this binder reached 42 million tons . In 2017, Brazil was the sixth largest cement producer in the world . The first batches of Brazilian-produced Portland cement had no mineral admixtures nor components other than clinker and plaster.
