Link to importance of concrete
Concrete has made building what it is today
Make sure you can partly improvise concrete it will help build fortifications and is paramount in the rebuilding of law and order.

Portland cement is the most common type of cement in general use around the world because it is a basic ingredient of concrete, mortar, stucco and most non-specialty grout. It usually originates from limestone. It is a fine powder produced by grinding clinker (more than 90%), a limited amount of calcium sulfate (which controls the set time).

Portland cement clinker is made by heating, in a kiln, a mixture of raw materials to a sintering temperature of about 1450 °C for modern cements. The aluminium oxide and iron oxide are present as a flux and contribute little to the strength. The major raw material for the clinker-making is usually limestone (CaCO3) mixed with a second material containing clay as source of alumino-silicate.

Normally, an impure limestone which contains clay or SiO2 is used. The CaCO3 content of these limestones can be as low as 80%. Second raw materials (materials in the rawmix other than limestone) depend on the purity of the limestone. Some of the second raw materials used are clay, shale, sand, iron ore, bauxite, fly ash and slag. When a cement kiln is fired by coal, the ash of the coal acts as a secondary raw material.

Skills will be the most saleable of items should SHTF

Skills and manual labor form the back bone of modern society although many would deny this.

Now is the time to learn a skill.

A friend recommended this link to me – this might be a necessary item to buy if you intend on growing grains, (I for one am looking at pearl millet – Link to seeds )… might be nice to make Corn bread or porridge with fresh ground corn or whatever grain.

I do need to mention though that this is why the Irish and English cultures were revolutionized by the discovery and importing of potatoes – they don’t need to be milled and made into bread and they produce more per hectare then grain, ( they don’t keep as long as grains do though) the best being red sweet potatoes if you live in South Africa – they grow like weeds – propagate themselves , and you can make a sweet syrup from them to sweeten anything by boiling down the water after cooking them and squeezing out the juice.

pumpkins also make great flour if dried and ground -( or so i hear ) and the yields are good.

Perma-culture VS Aqua-phonics
To feed my family is important to me and i have research many ways to do this.

I was looking at installing an aquaphonics system, as these can be hidden in plane site, and was considering a flotation method may be the easiest and least expensive (float the plants on the surface in styrene) but then the pond has to be really big and the plants have to have really small root systems.

After I did some research i discovered Perma-Culture and maybe its a good ideas to do permi-culture instead of aqua-phonics — they yield is lower but its way lower profile, requires less to setup and is lower tech so the natural balance is maintained, you also don’t have to worry about pumps, tanks etc.
the trade off is the lack of fish protein that would be a nice addition to the table.

Well i bought the book from this site and am working through it – maybe perma-culture is the way to go?
will let you all know how it goes.

In a word … “Boots”
A strong , good set of well worn in boots or shoes cannot be improvised . And any soldier will agree that your rifle and your boots are what make a soldier… I can fight naked as long as i have my boots . Yeah I know it sounds funny but any thing else can be made .. stolen or improvised but good shoes are complex and hard to make… Stock up … And learn the art of cobblering
