Embodiment 1

[0084] This embodiment provides a modification method of coral aggregate, and the specific steps are as follows:

[0085] Dosage of coating material

[0086] 1, screening points, 100kg coral aggregate sieves are 25kg having a particle size of 4.75-9 mm; 50 kg having a particle size of 9.5-16mm; 25 kg having a particle size of 16-19mm;

[0087] 2. Determine the value of each parameter in the calculation formula: Test the density of the slurry material used to treat coral aggregates, the present embodiment is used as a cement-based mixture of 0.47 as a coating material, and the density ρ is tested. p 2000kg / m 3 The loose stacking density of the coral aggregates is 973kg / m in turn. 3 965kg / m 3 ; 954kg / m 3 The thickness of the coating layer is 1 mm;

[0088] 3. The total coating material required for coral aggregates by grading is calculated from the grading average particle diameter, and the total amount of coated material is 55.8 kg.

[0089] Modification treatment

[0090] ...

Embodiment 2

[0093] This embodiment provides a modification method of coral aggregate, and the specific steps are as follows:

[0094] The first step: Screening, in Example 1.

[0095] Step 2: The coating material is equipped with Example 1, and the cladding layer thickness is selected for 2mm;

[0096] In the third step: According to the grading average particle diameter, the coated material required for each stage of screening is calculated, and the total amount of coating material is used in total is 111.6 kg.

[0097] Step 4: Take 100kg of coral sand, 111.6 kg of coated material is taken.

[0098] Step 5: Add coral sand in the mixer, first add a good water, stir 120s, to get the intermediate, then slowly add the powder while stirring, continue to stir 3 min, discharge, stack, and maintain 16 h at room temperature, Modified coral aggregate.

Abstract

The invention belongs to the technical field of civil construction materials, and particularly relates to a method for determining the use amount of a coating material in coral aggregate modification treatment and a modification method. Through strict theoretical calculation, the coral aggregate is highly matched with an actual test result, the coral aggregate can be accurately treated according to different surface coating design thicknesses, uniform coating of different aggregates is realized, no redundant slurry exists, the aggregates cannot be connected into clusters, large-area field paving is not needed, the coating treatment effect is comprehensively guaranteed, and the waste of the coating material is avoided. The method solves the problems that in a coral aggregate modification method in the prior art, the use amount of coating materials is often difficult to determine, if the coating materials are too many, due to the fact that fine components exist in the coral aggregate, the coral aggregate can be connected together by the coating materials, paving and maintenance must be conducted, site resources are occupied, and meanwhile waste of the coating materials is caused to a great extent, and if the coating material is too few, the phenomena of large resistance and non-uniform coating during stirring occur.

Description

Technical field [0001] The present invention belongs to the technical field of civil building materials, and specifically, a method of determining the amount of coated material for coral aggregate modification treatment, modification method. Background technique [0002] With the continuous advancement of ocean development strategy, the amount of infrastructure construction in the offshore island or coastal area has increased, as an important part of concrete raw materials, ordinary river sand, gravel resources are extremely lacking on the offshore island, from mainland transportation Stone raw materials will increase the construction cost and extend the construction period. Under the premise of do not destroying the local ecological environment, use the waste coral reef sand on the island reef to formulate coral aggregate concrete, which can not only save natural gravel resources, reduce transportation costs, shorten the construction period, but also effectively meet the develop...
