Chemical Admixtures - Cement
Superplasticizers, also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete. Flowing concrete is a highly fluid but workable concrete that can be placed with little or no vibration or

This report spurred further innovation in the field as innovators have had an easier time building on the work of their predecessors. It also provided support to technical experts around the United States as they began facilitating deployment of UHPC technology.
Influence of superplasticizer on strength of concrete
A mix design of M40 which is a high quality concrete mix is used in this study with its constituents OPC (Ordinary Portland cement) of 53 grade, Manufacture sand and coarse aggregates of sizes

the project No. LO1408 "AdMaS UP - Advanced Materials, Structures and Technologies", supported by Ministry of Education, Youth and Sports under the National Sustainability Programme I" and under the project No. FAST-S-15-2724 "Study of characteristic properties of Self Compacting Concrete" KAIT, supported
- Does super plasticizer affect the slump value developed for concrete?
- (0.2,0.4,0.6,0.8,1.0,1.2)% with cement content .The influence of variation in super plasticizer on the slump value developed for concrete is evaluated and also super plasticizer addition for concrete are examined by monitoring compressive strength as a function of curing period.
- Which type of super plasticizer is used in the project work?
- In the present project work grade of concrete M30 is used for the study and four type of super plasticizers ( Chloride free sulphonated naphthalene polymer, Naphthalene Formaldehyde condensate, Sulphonated Naphthalene formaldehyde condensates, Modified Naphthalene formaldehyde condensates ) are used for present study.
- Are recycled plastics used as coarse aggregate for constructional concrete?
- Efforts are made to minimize the quantities of materials that are delivered to landfills, "including the use of recycled plastics as coarse aggregate for constructing concrete" (SJB Institute of Technology, Bangalore).
- Can recycled plastic be used as a partial replacement of coarse aggregate?
- The project investigates the use of recycled plastic as a partial replacement for coarse aggregate in concrete. The maximum percentage of coarse aggregate that can be replaced with shredded plastic has been determined through a detailed experimental study.
- What is the compressive strength of plastic granules in concrete?
- From the graph, it is found that a compressive strength of up to 80% is achieved for a mix of concrete with up to 30% waste plastic as a replacement for coarse aggregate. The reduction in compressive strength of plastic replaced concrete is due to deficient bonding of plastic granules in the matrix.
- Can plastic waste be used in concrete?
- The project aims at using recycled plastic as a partial replacement for Coarse aggregate in concrete. The use of such plastic wastes in concrete will contribute to the sustainability of the concrete design and the natural environment.
