They sold us a lemon. The car broke 4 months after we bought it. Had to replace the transfer case ($4,000). The roof leaked when it rained ($500). Not to mention when we first got the car, all the...
When performing temperature tests, it is important to. use a good, accurate thermometer that is surrounded. by at least three inches of concrete. Take readings. quickly, noting that small samples lose heat fast. Concrete temperatures are affected by the mix-water. temperature, aggregate temperatures, cement type. and admixture type. Optimum concrete temperatures. will aid with setting, early strength development, proper curing and ultimately aid in achieving a higher. quality concrete. Hot concrete sets up rapidly, gaining.
Unfortunately, cracking is pretty common in concrete, especially during the first 30 days, while itâs curing. There are a number of reasons why concrete cracks. The most common is because concrete shrinks as the excess water evaporates and it hardens. Concrete can also crack if it dries too quickly. Weather conditions â extreme temperatures, rapid temperature changes or conditions that are too wet or too dry â also play a major factor in how well concrete cures. When the width of a crack exceeds 1/4â in width, it is probably time to seek professional assistance.
