What happens to concrete over time

Answered By: Peter Baker Date: created: Sep 25 2022

As concrete cures, it shrinks, which can cause cracks.

And as it reacts with water, concrete does something else – it creeps, or progressively deforms over time.

This has been known for decades, and it is included in every concrete-related calculation used in construction projects, so it’s not news..

How can I strengthen concrete without rebar

Answered By: Jaden Garcia Date: created: Sep 27 2021

It’s false economy to do concrete without putting in rebar and mesh. Rebar around the perimeter at the least, and mesh over the rest. Pull it up when pouring so it is not resting on the bottom of the slab. You don’t need the fancy rebar supports, a stone or broken brick will work just as well.

Does salt deteriorate concrete

Answered By: Seth Griffin Date: created: Nov 12 2022

The answer is yes, salt does indirectly damage your concrete driveways, patios and sidewalks. Bumps and potholes don’t just appear due to regular wear and tear – salt damages concrete over time by causing corrosion to occur under the surface, leading to discolored, cracked and crumbling concrete.

Does water weaken concrete

Answered By: Stanley Gonzalez Date: created: Jan 13 2022

The rule of thumb: One gallon of water will increase the slump of 1 yard of concrete by approximately 1 inch. This should only be taken as a rule of thumb as there are various other conditions, like temperature and air content, that will change the water required to increase concrete slump.

Does sugar really ruin concrete

Answered By: Gerld Martin Date: created: Nov 22 2021

As unlikely as this seems, sugar is actually a well known “retardant” of concrete and is often used to help adjust the setting times, especially in emergencies. … In the case of sugar, the setting process is slowed down because it interferes with the chemical reaction that causes cement to set when water is added.

Is poured concrete better than block

Answered By: Simon Cook Date: created: Apr 16 2022

Poured concrete foundation walls are arguably stronger than cinder block foundation walls. Without joints, poured walls possess a greater lateral strength, which essentially means they have a greater ability to resist pressure presented by water and the soil from the outside.

What happens if you add sugar to concrete

Answered By: Bryan Garcia Date: created: Oct 18 2021

The amount of sugar that should be used to keep concrete from fully hardening ranges from 1.0 to 1.5 percent by weight of cement. It is important to note, however, that the effect of sugar is not to keep the concrete permanently plastic, but to keep its strength at a low enough level so that it can be easily broken up.

Is it OK if it rains after pouring concrete

Answered By: Seth Morgan Date: created: May 22 2022

If the concrete is still fresh (around 2-4 hours after pouring), it’s important to cover the surface to protect it. However, once the concrete has been finished (between 4-8 hours after pouring), and has set hard enough for walking on, the effects of rain should be minimal.
