How in the old days they erected buildings for centuries without having cement

Everything that was built with mortar in the old days is much stronger and more durable than what is being built in our time. Not only ordinary people agree with this fact, but also experienced builders, archaeologists and historians. Buildings and structures erected many centuries ago are still found in all corners of the world today. Why, not having modern technologies, materials and equipment, did the builders of the vulgar succeed in this, but our contemporaries did not?

1. What is the reason

In the old days, cement had several varieties, the preparation technology of which was spelled out in specialized literature / Photo: crafta.ua

They knew about cement before, but this definition was applicable not to one specific solution, but to different ones. That is, we can say that the cement had several varieties. In fact, there was no cement in the form in which it is well known to us. But there were cement mortars that were prepared individually for a specific type of construction work.

The quality of these solutions was so high that many structures have been in operation for over a century, for example, the Saimaa Canal, built in 1856. in Finland. And this is far from the only example. Some designs are much older.

The workers prepared the mortar directly at the construction site in a specially constructed room, strictly observing the required proportions of raw materials.

But before starting the process of preparing the solution, a thorough study of the building materials used at a specific facility was carried out. The architect and the craftsmen were chosen based on the work they had done earlier. In addition, the builders were responsible for their work, its quality, both with their own property and with their heads. Therefore, options to do as long as they did not have.

2. How the solution was tested

After preparation, the solution was tested for strength in all cases. If the consumable was a brick, then ten bricks were laid out in a pile. After the solution grasps, they grabbed the upper one and lifted it up. In a situation where no more than three bricks fell off from below, the solution was called seed, which means strong. Provided that more bricks fell off, more cementum was added to the mixture.

In our time, no one bothers like that. And the buildings are more typical, except that the architecture is adapted to a specific consumer request. Mixed builders also do not follow many rules. Previously, it was believed that the solution has a "short life". Therefore, it must be used as quickly as possible. Perhaps the secret also lies in this.
