Quick questions on Reinforced and pre-stressed concrete: HSC Engineering Studies Civil Structures
2short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is reinforced concrete?Show answer
Reinforced concrete uses deformed bars (rebar) placed in the tensile zone of a member. The bond between concrete and steel relies on:
What is pre-stressed concrete?Show answer
Pre-stressing applies a compressive force to the concrete before service loads arrive. Under service load, the imposed tensile stress only partially cancels the pre-compression, so the concrete never enters tension and never cracks. There are two production techniques.
