Researching cement bricks, I found the following

I am not a historian. I’ve read a lot about history, and I think I know how to tell a good story. But when it comes to writing a story that’s accurate, I’m not sure.

When the subject is something like cement blocks, which are clearly not in dispute but which you can’t absolutely prove or disprove, you either have to make your point based on what other people say they thought at the time, or you make guesses that someone might eventually be able to check.

Because this is an online article and not a paper one, I can make my guesses more specific. The reason people said they were cement bricks was that they were sold as such by the people who made them: The person who wrote the article says he doesn’t have any source for the claim that the blocks were called “cement bricks,” but he says that of the many people who sell them, the majority say the blocks are called cement bricks. (The article also says that some sellers call them concrete bricks.)

So let’s assume we’re being told what other people thought at the time and that this is correct. It seems pretty likely that “cement brick” was a catchall term for any kind of block with cement in it. A quick search

I have tried to write a book on the subject of cement blocks, but it turned out to be a lot more difficult than I had expected.

Cement blocks in general and concrete blocks in particular are highly technical products. The whole process of making them is covered in tens of thousands of pages of technical specifications, and there are hundreds of pages on how to handle them when they are made. The rest is just filling in the blanks. Sometimes it’s not even that hard: as you can see from this blog post, anyone can write an article on cement blocks.

The difficulty comes from not knowing what you don’t know.

Researchers say there are only three blocks out there in the real world that will work: concrete, wood, and cement. I’ve never seen a wood block work. But I’ve found concrete and cement blocks that worked for me.

I can give you a scientific explanation for how concrete and cement bricks work, but it’s not important. The purpose of this post is to show that it is possible to make a brick that works better than any other brick.

To be clear, I have not created the best brick in existence; but I have made an excellent one, which is at least as good as the others out there. “The best” isn’t actually important either. What’s important is whether you can build something with a better experience than anything else on offer; and right now, at least in my neighborhood, I do.

The main scientific explanation for why these bricks work is called the “strength-to-weight ratio.” This ratio turns out to be pretty darn close to optimal if you have a 3:1 ratio of strength (ie, weight) to volume (ie, size). That’s the way bricks are usually made because most bricks are based on specific shapes.

My brick is different: it is not based on a standard shape like circle

Years ago I worked as a researcher on the topic of cement. I knew that cement blocks were supposed to be lightweight, inexpensive and strong. But I wanted to figure out why they weren’t. What I found was that cement is made of sand, clay and limestone. And these materials were what were being used up, not the limestone.

The reason the blocks are so cheap is that they are really bricks: pressed sand and clay bricks. There are several hundred different kinds of brick, but most of them have only one function: to keep a load of building materials from shifting or escaping during construction.

Cement blocks don’t do this; they just stand there looking good on the wall. So it makes sense to make your own bricks by buying cement and mixing it with sand and clay in special presses like this one from Gavilon .

There’s no good reason to believe that concrete masonry was invented in the Middle Ages. The idea of using a mixture of mortar, sand, and cement to make a building stronger is as old as history, and it has been used for centuries.

The earliest known reference to concrete is from the Chinese Zhou Dynasty (1046-256 BC). But concrete masonry is one of those things that sounds like an obvious idea until you start researching it. It’s hard to find any good references on how it was done before the 20th century, because people were doing it without documentation for those centuries.

I spent days reading about the history of cement and concrete, but I couldn’t find any evidence that ancient cultures knew about them. I found more references in medieval books than in any other period. But then I noticed something: these books always talked about making cement bricks, not using them. They had nothing to say about how they were used.

Then my wife pointed out that modern cement isn’t really different from what was being made in the Middle Ages – they just don’t call it cement.

I am writing this because I believe it will be useful to many people. It is especially useful for those who are confused about how cement works and how to build with it. In recent years, the construction industry has been in a state of flux, and much of the confusion seems to be coming from misinformation about cement.

First of all, let’s get one thing out of the way. Cement is not a chemical. It is a mixture of sand, clay, and water. It is a physical mixture. If you put sand, clay, and water in a machine that mixes them together and turns them into cement, you are not creating a chemical; you are making cement.

The reason I say “not a chemical” is that chemistry is an extremely complex science with many branches, each one with its own subtle interpretations and applications that may or may not agree with each other. Cement is chemistry with the complexity stripped away so we can understand it clearly. It’s why I call it “the simplest thing that could exist.”

The cost of concrete, measured in dollars per ton, has risen by a factor of 100 over the last century. That’s largely due to the invention of higher-quality cement and concrete. But what is a ton, anyway?

It’s not an easy question to answer. In this blog post I’m going to look at how a ton of these bricks stacked up against two other measures of weight: the kilogram and the pound.

A ton of steel is defined as a mass of 1,000 kilograms. That’s no longer exactly true; today it is almost 1,100 kilograms. But that doesn’t affect my calculations here.

A ton of water weighs about 1,000 kilograms on Earth (but not exactly; see below). A tonne is slightly more than 2,205 pounds on Earth. And an acre is about 447,840 square feet on Earth.

The formulas for calculating the various weights are different for every planet in the solar system, but to make any sense of this I need only stick to Earth.
