There’s a lot to mixing concrete!
As you can see there is more to the proper mixology of cement and water to form concrete and many different types of cement and other ingredients that are used in the mixture. Make sure to measure your ingredients as per instructions to get the results you want. You want to make sure the cement and sand are completely mixed before adding your gravel. The gravel should be well coated by the cement and sand mixture. After this is accomplished make a small trench inside the mixture and add half of the measured water then use a hoe to pull the cement mixture into the water. Once you get that water absorbed make another trench and pour in the remainder of the water and mix until completely absorbed. Now you can allow it to cure.
