3. INTRODUCTION
Centre of ash utilization technology
and environment conservation
(CASHUTEC) shaktinagar. It is a
leading institution for promoting,
propagating and implementing, Eco-
friendly, low cost and innovative
technologies on intensive use of fly ash
and municipal solid and liquid water
management. this is also knwn as
NIRMITHI KENDRA.
CASHUTEC

4. CASHUTEC NIRMITHI KENDRA INVOLVES:
 Quality control & Construction Material Testing Services.
 Production of Fly Ash based pre-cast, Low-cost
Construction Materials.
 Implementation of high volume fly ash utilization in civil
constructions.
 Research and development (R &D)
 Swatch Bharat Mission: Toilet Construction
 Training and Internship activity
 Production of materials by using Fly Ash

5. VISIT TO PRODUCTION UNIT
Producing more than 40 low-cost pre-cast high volume fly ash based construction products for
captive consumption as well as for sale in the open market in most competitive prices to
stimulate the local supply of sustainable and reusable construction materials and technologies
and to improve local resource use to support sustainable management and socio-economic
development at the local level.

6. WORKSHOP ON GEOPOLYMER CONCRETE

7. PROPERTIES OF GEO POLYMER CONCRETE:
Geo-Polymer concrete: concrete in which an organic polymer serves as the
binder.
Polymer concrete is a composite material in which the aggregate is
bound together in a matrix with a polymer binder. The composites do not
contain a hydrated cement phase, although Portland cement can be used as
an aggregate or filler.
Advantages of Geo-polymer Concrete:
 Geo-polymer concrete has high compressive strength.
 It has high tensile strength.
 Also has low creep.
 Low drying shrinkage.
 It has resistant to heat and cold.
 They are chemically resistant.
 It is highly durable.

10. TESTS ON AGGREGATE:
 Sieve Analysis
 Aggregate Crushing test
 Aggregate Impact test
 Aggregate Abrasion test
 Shape test (Flakiness index test and Elongation
index test)
 Soundness test
 Specific gravity and water absorption test

11. HERE ARE SOME TESTS CONDUCTED BY INTERNS:

12. Crushing Value Test Coarse Aggregate:
Apparatus:  A compression testing machine.
 IS a sieve of sizes 12.5 mm and 10 mm.
 A cylindrical metal measure.
 A steel tamping rod.
Procedure:  The sample of coarse aggregate is sieved through a 12.5
mm IS sieve and retained on a 10 mm IS sieve.
 A sample of aggregate is taken in a cylindrical metal
measure, and it is tamped 25 times using the tamping rod
to ensure uniform compaction.
 The aggregate is then placed in the compression testing
machine and subjected to a compressive load until it
breaks.
 The maximum load (P) at which the specimen fails is
recorded.

13. Impact Test Coarse Aggregate:
Sample Preparation:  A representative sample of the aggregate material is
collected. The sample should be large enough to provide
a statistically significant result.
 The sample is cleaned of any dust, dirt, or impurities that
could affect the test results.
 The aggregate is usually dried in an oven to ensure it is
in a dry and stable condition before testing.
Test Procedure:  A specified weight of the prepared aggregate sample is
placed in the testing machine.
 The machine is set to rotate at a specific speed, which is
usually around 30 to 33 revolutions per minute (RPM)
for the Los Angeles Abrasion test.
 During rotation, the steel hammers or rods repeatedly fall
onto the aggregate within the drum.
 The test continues for a predetermined number of
revolutions or until the aggregate has undergone a
specified level of abrasion or impact.
