What makes cement set faster?
Add warmer water. As one of the key ingredients in concrete, water is essential for the curing reaction to occur. The curing time can be hastened by using a slightly warmer water in the mixture as this will encourage the reaction to occur more quickly – do not, however, use blazing hot water as this could be damaging.

Tips
Commercial cement is a mixture of limestone and oyster shells (along with a blend of other shell types) that has been superheated to remove the carbon dioxide.
Warnings
Concrete can stain or stiffen any clothing that it comes in contact with, especially if it’s allowed to dry. When making concrete, be sure to wear clothing that you don’t care about.

Overview: Materials and Tools
Protect your skin and eyes! The cement in concrete is caustic and can cause burns if it gets on your skin.
Before You Begin Mixing Concrete
For most small jobs around the home, bagged concrete mix is the most convenient and least expensive way to go. You can use it for fence post footings, deck footings and even small concrete pads. For jobs requiring more than about 30 bags, consider ordering “ready-mix” concrete from a truck instead.
Making Concrete: Slice and Dump the Bag
Set the bag of concrete mix in one end of the wheelbarrow and slice it open with your hoe. Dump the mix from the bag and pull out the paper bag.
Making Concrete: Add a Measured Amount of Water
One of the most common mistakes beginners make is to add too much water and end up with concrete that's thin and soupy. Here are a few tips to avoid the problem and find the right concrete mix ratio.
Mixing And Ratios
Mixing concrete may sound easy easy, but it takes careful measuring and thorough mixing to get it right. First, measure the ingredients out. Be careful because if you want consistency from batch to batch then the ingredients have to be exactly the same. Mix together the cement, sand and aggregate really well until you’ve got a finished dry mix.
Getting the Correct Consistency
Concrete that’s too runny will reduce the compression strength which causes it to deteriorate much more quickly over time. Too little water makes the job harder but it doesn’t reduce strength. You need just enough water to form a paste and bind the components together but not so much that the mix feels like soup.
Directions
Mix all of your dry ingredients in a wheelbarrow or mixer. Approximately 1 part cement, 2 parts sand, and 3 parts aggregate. Mix enough water to make a smooth consistency. There should not be any lumps and the mix shouldn’t be soupy.
The Curing process
Soon after the aggregates, water, and cement are combined, the mixture starts to harden. Portland cements are hydraulic which means they set and harden through a chemical reaction with water call hydration. During this reaction, a node forms on the surface of each cement particle.
Summary: How To Make Concrete
To make concrete, mix cement, sand, aggregate (course gravel), and water together. The basic mixture is one part cement, two parts sand, and three parts aggregate. Mix all the dry ingredients together really well before you add any water. A good dry mix is very important if you want a finished concrete with consistent strength and color.
Step 2: Measure the Concrete Recipe Ingredients
While there is a bit of leeway, making your own concrete requires following a certain recipe.
Step 3: Mix the Ingredients
Use a shovel to mix the ingredients in the wheelbarrow. Be sure to scoop from the bottom and scrape the sides periodically so you don’t miss any pockets of unmixed materials. The goal is to fully incorporate all the materials before adding water in the next step.
Step 4: Add Water
Use the shovel to create a small reservoir in the middle of the dry mix. Use the larger bucket to add water to the mix, taking care to mix it in as you go. Keep adding water until all of the mixture is wet and the concrete is the consistency of cookie dough.
Step 5: Adjust the Mix
Mixing concrete is a process, and adding water can be trial and error. If the mix is too dry, simply add water a little bit at a time until it reaches the ideal consistency.
