[0183] 3. Test Experiment

[0184] 3.1. Anti-insect experiment

[0185] 1) Experimental materials: 600 kg of environmentally friendly high-performance concrete (including cement, sand, and gravel) (the mass ratio of cement, sand, and gravel is 1:2.13:4.23);

[0187] 60 1*1*1m 3 A removable container;

[0188] 60 5*5*5m 3 A container containing 20 kg of soil;

[0189] 6,000 termites.

[0190] 2) Experimental steps:

[0191] ① Place 100 termites in a container containing 20 kg of soil and place it outdoors for 7 days;

[0192] ②600KG of environmentally friendly high-performance concrete and 60KG of water are divided into 60 portions, each portion contains 10KG of environmentally friendly high-performance concrete and 1KG of water;

[0193] ③ Take 5 kg of each of the environmentally friendly high-performance concrete admixtures prepared in Examples 1-3 and Comparative Examples 1-3, and divide the 5 kg of environmentally friendly high-performance concrete admixtures into 10 portions, each portion weighing 0.5 kg;

[0195] ⑤ Evenly mix 0.5 kg of environmentally friendly high-performance concrete admixture, 10 kg of environmentally friendly high-performance concrete and 1 kg of water, pour them into a demoulding container and let them stand for forming. Then, take out 60 concrete blocks, remove the demoulding container, and place the concrete blocks in the original position of the demoulding container;

[0196] ⑥ The number of termites escaping from the container containing 20 kg of soil was recorded by a camera for 5 days, and the average value was taken for the environmentally friendly high-performance concrete containing the environmentally friendly high-performance concrete admixture prepared in the same embodiment or the same comparative example, and the record was as follows Table 1:

[0207] ④ The crack rate of the environmentally friendly high-performance concrete containing the environmentally friendly high-performance concrete admixture prepared in the same embodiment or the same comparative example is calculated and recorded in the following Table 2:

[0208] project Crack rate Example 2 0％ Comparative Example 4 1％ Comparative Example 5 2％ Comparative Example 6 4％
