The Korea Construction Association announced the 2020 supply and demand forecast for 10 major construction materials such as ready-mixed concrete, rebar, and cement. The decline in construction orders, which started in 2017, is expected to continue for four consecutive years until 2020, and the overall demand for materials is expected to decrease in 2020 following 2019. In particular, it is predicted that the overall decline in material demand will continue due to the tightening of regulations on the housing market and the deterioration of the private housing sector construction market.

Looking at the 2019 demand performance by material, tile showed the largest decrease at 12.2% compared to the previous year, and overall demand decreased for most materials except asphalt concrete, such as ready-mixed concrete 6.9% and concrete pile 6.6%. This year, although the construction investment in the civil engineering sector is expected to increase slightly compared to the previous year after stopping in 2019, the decline in the private housing market is expected to have a negative impact on the overall construction investment.

By major material, due to a decrease in new construction starts, concrete piles are expected to be 5,400 thousand tons (8.8%↓), tile demand is 133,91 million m² (7.2%↓), and cement demand is 51,100 thousand tons (6.6%↓). Demand for materials is expected to decrease in all directions, with a 4.2% and 4.1% decline, respectively.

First, in the case of the absorptive plate unit 110, as shown in FIGS. 1 and 2, a pair of vertically standing to form a body in which a front face and a rear face are spaced apart in parallel to each other. will correspond to

That is, when the individual blocks are stacked up and down by configuring the front and rear faces on the three-hole block, the configuration that forms the main load support and proof force is just the absorptive plate part 110 . corresponds to

Absorbing plate unit 110 may be composed of concrete or cement, which will be described later.

1 and 2, in the case of the cross-bridge unit 200, each of the pair of absorbing plate units 110 as described above is interconnected, and a hole portion H is formed in a space spaced apart from each other. configuration to do so.

In the case of the cross-bridge unit 200, if the block is a three-hole block, the four cross-bridge units 200 are spaced apart from each other and arranged in parallel with the absorptive plate unit 110 spaced apart in pairs. can Of course, it goes without saying that the number of cross-bridge units 200 may be arbitrarily reset by setting the number of hole units H.

In the case of the absorptive plate part 110 having the above configuration, by selectively adjusting the viscosity of the compound part 112, the porosity of the stone part 111 is selectively selected for each region along the preset virtual line (L). will be regulated with

Here, in the case of the preset virtual line L, it can be defined as a conceptual regional division line that cannot be observed with the human eye, which can be revealed by the discontinuous difference in porosity.

In addition, in the case of a preset virtual line (L), the boundary is extended to the entire surface of the absorbing plate part 110, that is, the entire outline of the body unit 100 is a preset virtual line (L). can be scalable

When the preset virtual line is formed as a closed curve, it may be composed of one divided area, and as shown in FIGS. 4 and 5 , one divided area may be divided left and right or up and down.

One partitioned region may have a relatively dense porosity, and the other partitioned region may have a relatively small porosity.

As such, the dense area and the small area can be divided horizontally on the left and right, as well as vertically.

In addition, in the case of the dense and small porosity, it is possible to continuously change the dense and small regions up and down even within one region.

Through this, as shown in FIGS. 7 and 8 , the absorptive plate unit 110 can be arbitrarily set so as to have a region partitioned by a preset virtual line L to cross each other.
