7 helpful tips for concrete solutions Concrete is a very easy material to manage, however, you can run into many big problems if it is working properly. This is why you need an expert guide like Concrete Solutions NZ that will give you permanent solutions to solve a common problem you will appreciate.
Here are some concrete problems you need to look out for such as, 1) Discoloration: Concrete discoloration can appear if there are sudden changes in the cement materials. It is that finishing is rushed or calcium chloride is added. Here is the solution to solve the discoloration problem:
Identify the ready mix first Prepare your uniform subgrade Wait until all the water is evaporated before finishing concrete Avoid any hard troweling on an exterior surface
2) Scaling: Another very common concrete problem is scaling. It only occurs when the concrete surface is broken and keeps peeling away. Scaling can also appear if non-air entertained and concrete is exposed.
Here is the solution to avoid concrete scaling: Use a low slump air from 7 to 8 percent in an entrained mix Wait until the water becomes evaporated from the surface Never to use salt or any other chemical during the winter season
3) Crazing: One of the most essential tips you can follow of Concrete Solutions NZ is to avoid crazing which can occur many interconnected cracks or when cement paste shrinks and comes upon the surface.
Here is the solution to solve crazed concrete: Cure the concrete in a timely matter Use moderate slump concrete without segregation
Do not dust dry cement on the surface while water is in it Never to sprinkle water over the concrete while finishing 4) Cracking: Concrete can be cracked easily, it is unpreventable, However, it can be controlled and this one of the main problems when constructing. Cracking can be occurring due to thermal contraction, drying shrinkage, applied loads, and subgrade settlement. Here is how to reduce cracking in concrete:
First, remove soft spots and organic material in the subgrade Slope the subgrade with proper drainage Design a flexible concrete pavement to accommodate movements and load Now install concrete joints by sawing or tooling Place, finish and cure concrete Do not overwork on a concrete surface Minimize the water content until its aggregate
5) Curling: Concrete curling only occurs when both moisture and temperature in the top and bottom of the surface resulting in base become unsupported. Here is the Concrete Solutions NZ to avoid concrete curling:
Use proper curling techniques Place concrete joints firmly Use lower water content Ensure proper bonding while applying on thin toppings Use enough steel reinforcement in the slab Place concrete on a damp to water bleed out on top of a slab
6) Spalling: Spall is a thin layer that occurs on the surface and peels off from the bottom side. This only happens when over troweling is applied.
Here is the solution to prevent spalling: Use sand on the spalled area Replaster if the area is large Read More: How to choose the Right Concrete Suppliers for your Construction Project 7) Popping up or floating: Water pressure is something that can float with it. Concrete pools are most likely to float because its overall gunite shell is broken and can lift. Here is to perfect solution to avoid floating: Try to install a hydrostatic valve Maintain it until the concrete is soaked properly
