There was no cement in ancient times, so how was the Great Wall built? Without cement, how to build the wall?

It is true that there was no cement as a building material in ancient times, but without cement, ancient people still had the wisdom to build the Great Wall as a bronze wall. In ancient times, there was a special technique, which has been passed down to the present time, and it is said to have been made from glutinous rice mixed with certain materials, which was used to build houses or fortifications as hard as cement.

In fact, in ancient times, the use of cement, that is, this material is very little, because most of the structure is based on wooden structures, only in the construction of walls or the construction of underground mausoleums will be used in this building material. And the materials used by ordinary people's homes are basically yellow mud used as paste to build houses.

Of course, there are some dignitaries who will choose to use this building material when they choose to build a house, after all, this kind of building material is too expensive, the general public can not afford it.

In fact, I also very envious of the skills of ancient craftsmen, in ancient times, the construction of houses, most of the wooden materials as the basis, and in the construction of the house does not use a nail will be able to build the house completed, and can stand for hundreds of years do not fall. Take the Forbidden City among the house as an example, there are many houses are hundreds of years have been handed down to today, and this technology, has been lost.

So the ancient craftsmen had a very high level of skill, but it was not passed down better. The bricks used in ancient times were different from the red bricks we use now, they were bigger, stronger and more durable, but a little heavier, and they were perfect for building city walls. And the ancient brick is rarely made through the firing completed, so the durability is a little higher.
