Purpose of Concrete: S.S.S's main objective is to help rebuild the buildings and homes destroyed in the tragic earthquakes in Port Au Prince, Haiti and Concepcion, Chile. We will put up stronger structures that will hold up to future catastrophes and that will leave the minds of the residents at rest, and not constantly worried that they are in danger of losing everything again.

Recipe Ideas w/ sources: introduction.

Due to the devastating earthquake that struck Haiti on January 12, 2010, the world took into serious consideration of what should make up concrete. Why did all of those buildings fall so easily is debatable. Some say the proportions were off in order to avoid high costs others say that it was all due to the magnitude of the earthquake. In order to avoid further digression our Company, Strong, Safe and Sound will inform you about the correct and affordable way to make concrete and why we must be considered every time you wish to build a home for your family and children and to give back to the children that lost their parents a sturdy home to live in for future generations to come. Our company is the most efficient and practical method of construction. We use a newer and better design of concrete that is designed to hold up to the worst of disasters.

4 parts of grey sand 2 1/2 parts portland cement 1 3/4 parts water For our stronger designs of concrete we lower the water-cement ratio. Concrete mix idea:

if there is a batch that consists of two bags of cement, 5.5 cubic feet of sand, and 6.4 cubic feet of coarse aggregate. Mix the sand and cement together first, using the following procedure: 1. Dump 3 cubic feet of sand on the platform first, spread it out in a layer, and dump a bag of cement over it. 2. Spread out the cement and dump the rest of the sand (2.5 cubic feet) over it. 3. Dump the second sack of cement on top of the lot.

- the use of alternate layers of sand and cement reduces the amount of shoveling

Components of a concrete mix:

- Water - Aggregates (rock and sand) - Portland cement

Important properties of concrete:

- The mix is workable with - All the desired qualities of the concrete when it is hardened are met - Use of water to be reduced to reduce the cement requirement because the more cement needed means the more water


 * Ease of placement
 * Compaction without segregation
 * Early age strength
 * Long-term mechanical properties
 * Permeability
 * Density
 * Heat of hydration
 * Toughness
 * Volume stability
 * Long life in severe environments
 * Depending on its implementation, environmental [|[1]]
