It is completely acceptable to bury/embed both hard drawn and annealed copper water tube in concrete. Decades of satisfactory service experience with the use of copper tube for in-floor radiant heating systems, water distribution systems and snow melting systems attest to the compatibility of copper tube embedded, encased or in contact with concrete.

To investigate the effect of copper ion on the hydration process of high ferrite cement, the ground and screened clinkers were mixed with 4.74 wt% CaSO 4 ·2H 2 O (analytical grade). The cement pastes with a water-to-solid weight ratio of 0.3 were prepared, then cast in 20 mm*20 mm*20 mm molds and vibrated during casting to …

The cement paste after mixing for 1 min was transferred to the syringe and then weighed as W 1. An object with a weight of 5 kg was applied to squeeze the cement out. The weight of the syringe and the residual cement was recorded as W 2. The injectability of Cu-CPCs was then calculated by Eq. (2): (2) Injectability % = 100 × W 2 − …

A: Copper is unlikely to react with the limestone or concrete, as long as it isn't too alkaline. The hard water deposits that sometimes build up in copper pipes are made up mostly of calcium carbonate, just like limestone. However, it might still be a good idea to run the copper through a PVC sleeve. Copper is relatively soft, so long-term ...
