Dunagan Test Set Manufacturer,Supplier and Exporter in India
Product Code : EL-CL-8853
Jlab Export is a leading Dunagan Test Set Manufacturer,and suppliers in India
The Dunagan test works out how much cement, aggregate and water a sample of fresh concrete holds, by washing it through sieves and weighing the parts in water. This cased set carries the balance, buckets, basket, weights, scoops and sieves for the test. It also serves for specific gravity, absorption and silt checks on fine and coarse aggregate.

How the Dunagan Analysis Works
A sample of fresh concrete is weighed in air and then in water. It is washed over the no. 100 sieve, which lets the cement and fine silt pass. The no. 4 sieve then splits the coarse aggregate from the sand, and each fraction is weighed in water in the basket. With the specific gravities of the materials, these masses give the cement, sand, coarse aggregate and water in the original sample.
Lab Exercises with the Dunagan Set
A class can take a sample from a batch made in the Laboratory Concrete Mixer and check whether its proportions match the mix that was weighed out. Any differences show how sampling and mixing affect the result.
On its own, the set measures silt in sand by washing a weighed sample through the no. 100 sieve and drying what stays on it in a Drying Oven. The basket and balance also give the specific gravity and absorption of aggregate. The same sand can be screened for organic matter with the Organic Impurities Test Set.
Frequently Asked Questions
What does the Dunagan test find?
It finds the proportions of cement, fine aggregate, coarse aggregate and water in a sample of fresh concrete. Washing and weighing in water separates the parts, and their specific gravities turn the masses into proportions.
Which sieves come with the set?
Two 203 mm (8 in) sieves. The no. 4 mesh sieve, 102 mm (4 in) high, parts coarse aggregate from sand. The no. 100 mesh sieve, of standard height, lets cement and silt wash through.
What balance and weights are included?
A balance of 5 kg capacity, a 2000 g brass weight set and 1 kg slotted weights. Three scoops come with them for handling samples while weighing.
Can it test fine aggregate as well as coarse?
Yes. The set covers specific gravity and absorption of both fine and coarse aggregate, plus silt determination on sand.
How does it differ from the Coarse Aggregate Density Test Set?
The Coarse Aggregate Density Test Set is for coarse aggregate alone, weighed on a larger buoyancy balance over a water tank. This cased set also tests fine aggregate and adds fresh concrete and silt analysis.
