Phthalate Plasticizers. Phthalate plasticizers are a group of chemicals derived from phthalic acid that are commonly used to make plastics such as polyvinyl chloride (PVC) more flexible, transparent, and durable. They

A good plasticizer makes concrete or mortar flow in a way that is different from how an air-entraining agent does it. But some plasticizers also add air to the material, making it easier to work. A good plasticizer should add 1% to 2% of

What makes a good plasticizer?
A good plasticizer makes concrete or mortar flow in a way that is different from how an air-entraining agent does it. But some plasticizers also add air to the material, making it easier to work. A good plasticizer should add 1% to 2% of the air to concrete at most because adding air to concrete makes it less strong.
How much plasticizer should be used in concrete admixture?
Typical plasticizer dosage rates range from 0.3-1.5% by weight of cementitious material. Overdosing can negatively impact strength. Trial batches should be tested. There are several classes of plasticizers are used as admixture in concrete . some important types of plasticizers used in concrete:
What is a good plasticizer dosage rate?
Underlayment and overlay – Provides smooth surface finish. Typical plasticizer dosage rates range from 0.3-1.5% by weight of cementitious material. Overdosing can negatively impact strength. Trial batches should be tested.
How much air should a plasticizer add to concrete?
A good plasticizer should add 1% to 2% of the air to concrete at most because adding air to concrete makes it less strong. The primary purpose of hydrophilic plasticizers is to improve the concrete’s plastic and flow properties, as evidenced by their increased wet ability. This plasticizer makes a lot of air get into the concrete mix.
What is a plasticizer used for?
Plasticizers are commonly used with polyvinyl chloride (PVC) and concretes. Plasticizers serve several crucial purposes in civil engineering materials: Workability – Plasticizers allow concrete to flow more easily into molds and around rebar during pouring. They make the concrete more malleable and improve slump. This makes large pours easier.
How accurate is NMR calibration for plasticizer in PVC?
Every plasticizer used will require a different calibration. By taking 10 consecutive repeats of the same sample at 35%, the precision of measurement is found to be +/- 0.06%. Figure 2. NMR calibration for plasticizer in PVC.
