RCC Pipes
Manvi Infra & Projects - RCC Pipes
Process of
Manufacturing
The concrete mixture for the RCC spun pipe is prepared in proportion of 1:2:5:2:5 of cement stone, metal and sand respectively. The cement concrete is fed into the moulds during rotation which spreads inside evenly. The time required for completion of this operation depends upon the diameter and class of the pipe. The pipes are kept in the mould for 24 hours.
On the following day the pipes are removed from the moulds and submersed in water in the curing tank for about 10 days depending upon the class of the pipe. The specimen of the pipes are subject to the following tests Hydrostatic pressure test
edge
Bearing test
Three edge bearing test is a destructive load test to determine the strength of a concrete pipe. Strength is main characteristic of concrete Hume pipes. Durability and strength both are measured with Three Edge Bearing Test. (code reference: IS 458:2001)
Hydrostatic
Pressure Test
This test is conducted by applying water pressure from a pump to the pipe covered on all sides to find how much pressure the pipe withstands before it leaks.
The pipe quality is approved if the tested pressure is compatible with the ISI specifications. (code reference :IS 458:2001)
Test for
Permeability
Cement will mix with more water than is required to eventually combine during hydration of cement paste. As such, some voids will be left behind after the hydration process which affects the strength and durability of concrete. With the presence of air voids in concrete, it is vulnerable to penetration and attack by aggressive chemicals.
Good quality concrete is characterized by having minimal voids left by excess water and therefore, water absorption test for precast concrete pipes is adopted for checking the quality of concrete in terms of density and imperviousness. (code reference: IS 458:2003)
SOURCE OF
Materials & its Genuinity
CEMENT: We use various brands of cement in OPC 53 grade like Sagar cement, UltraTech cement, KCP cement for production of material at our factory out of which we chose Sagar cement as our primary source for cement. Sagar Cement is extremely easy to work with and consistently produces excellent results. This consistent quality, versatility and strength make it as our choice to choose for (ATTACHED LAB REPORTS FROM ANNOR TEST LABS & ENGINNERING SERVICES).
SAND: River Sand that we used is from River Beds and Banks. It is usually very fine in quality and has a white-grey colour. River Sand is good for all construction activities like concrete production and plastering as it is well graded. As per the Indian Standard codes, sand used inpreparation of concrete and in plastering should ideally confirm to IS-383 Zone-II.
AGGREGATES: We use aggregates in size 10mm, 1 2mm and 20mm in our production ranging from diameter 150mm to 2000mm are procured from reliable vendor within our surrounding area.
STEEL: We use different gauges of mild steel wire ranging from 4mm to 14mm gauge as a spiral cage in reinforcement as per IS 458:2003 standards and also longitudinal rods in diameter ranging from 4mm to 12mm rods.
