Abstract. Expanding cement is cement to which an expansive component is added. It is a true expanding cement, since the expansion occurs after the cement has set. As expansion occurs, the cement is restrained by the formation and by the casing so that expansion produces a self-stress in the cement. As casing diameter is reduced by …

As a weak, dilute acid, vinegar will cause only minor damage to concrete but can take the shine off polished surfaces. It can, however, be used to remove small amounts of cement from tools. The interaction of vinegar and concrete comes down to chemistry. If that gives you nightmare flashbacks to high school, don't worry.

Premix the concrete to a stiff consistency before you shovel it into the hole. This gives the concrete mix the bulk to displace water. The concrete mix will also set if you pour it into the hole directly from the bag, but the block it forms won't be as uniform or as strong. Let the concrete cure for at least a day before you remove the braces ...

Yes, concrete can also expand in the winter due to changes in temperature. Concrete is a porous material that is capable of absorbing and releasing moisture. When the temperature drops, the moisture in the concrete contracts, causing the concrete to contract along with it. This is known as thermal contraction.
