Can you test a concrete core with rebar?
Rebars always make difficulty in coring of reinforced concrete structures. Sometimes it is not possible to core from plain concrete areas. … Also some cylindrical samples were made and tested with placed rebars.

Can i epoxy over concrete stain?
Epoxy garage paint can be used over concrete stain, provided the proper preparation work is done. As with many painting projects, successfully epoxying a garage floor is mostly about preparing the surface to receive the epoxy.
How to estimate amount of concrete needed?
Multiply the width times the length times the height (W × L × H), or use our volume calculator to find the cubic feet. Convert the volume to cubic yards from cubic feet. To do so, divide the cubic footage by 27 to get the yards of concrete needed.
Which is better asphalt or concrete?
Concrete is more durable than asphalt. Because it is a less flexible material, it cracks in freezing temperatures, and many people turn to concrete patching products. … Though it is more durable overall, when damages do occur, concrete repair is harder and costlier than asphalt repair.

How much weight can my concrete driveway hold?
Most residential driveways typically use concrete compressive strengths of 3,000 to 4,000 psi and commercial and industrial 5,000 psi. The higher the compressive strength, the more weight it will support, the greater the cost, and the longer it will last.
Is apartment ceiling concrete?
Instead of covering the concrete slabs that are used to construct newer buildings, developers often choose to leave them as-is (with a coat of paint) so as not to lose precious inches of ceiling height. In these apartments, ceilings are the underside of the concrete slab.

What strength is lean mix concrete?
As far as Civil construction is considered, the ratio of concrete is 1: 3: 6 (M-10) and below, which is called lean concrete. Generally 1: 3: 6, 1: 4: 8 and 1: 5: 10 mixes are used for lean concrete mixes. M-5 grade concrete will give a total characteristic strength of 5 MPa.
Can you grow vegetables on concrete?

How does translucent concrete work?
Translucent concrete (also: light-transmitting concrete) is a concrete based building material with light-transmissive properties due to embedded light optical elements — usually optical fibers. Light is conducted through the stone from one end to the other. Therefore, the fibers have to go through the whole object.
How to protect concrete statues?
