NANOMODIFIED CONCRETE COMPOSITIONS.

NEW WAY OF ABC UNIT APPLICATION

The one of the main problems of contemporary construction material

production is problem of obtaining concrete compositions of high quality. The

possible way to resolving this problem is modification of a cement stone

structure that allows using all durability potential of the crystalline hydrates and also

increases the quality of all concrete components.

We have investigated the ways of concrete quality improvement by using

nanotechnologies and nanomaterials such as magnetic activation.

Let`s consider the results of application of ABC

unit (Intensifier of Technological Process by PC

GlobeCore) during the production of fine-grained

concrete compositions.

We have used standard methods to research the

durability characteristics and physical and mechanical

properties.

We have made the test of mixing concrete

components four times. This was made in order to

provide homogenization of concrete components

including nanoagents.

To intensify the process of components mixing

in ABC unit we have used ferromagnetic particles

covered by polymer coating. In other cases we have

investigated the influence of Intensifier of

Technological Process on production of magnetic

mixing water.

Solutions of the one composition were made from the same fillers. Mixture

ratio of components is 1 to 3. Cement-water factor ranged from 0.6 (for examples

which were hydrated by the magnetic water) to 0.8 (for examples which were

hydrated by the ordinary water), content of nanoagents ranged from 0.5% to 2%.

Time of water processing by the variable magnetic field is from 2 to 5 seconds.

Results of test show that even small quantity of carbon nanoparticles and their

application increase the complex of properties of concrete.

The maximum degree of the test sample durability can be obtained by adding

of additive agent whom is equal to 1% all batching mass.

General view of The Intensifier

of Technological Process ABC-100

by PC GlobeCore

Durability peak is in the range from 0.5% to 1% of nanoagents content in

concrete. Interesting that the durability of nanomodified samples exceeds the

durability of control samples during compression testing in 5.8 times and during

bending test in 5.1 times.

Results of testing you can see at the below figures.

Figure 1 – Dependence of fine-grained concrete compositions durability during

bending test:

1 – compositions prepared by using magnetic water;

2 – compositions completely prepared by ABC unit

Figure 2 – Dependence of fine-grained concrete compositions durability during

compression test (contain nanoagents):

1 – compositions prepared only by using magnetic water; 2 – compositions

completely prepared by ABC unit

Figure 3 - Dependence of fine-grained concrete compositions durability from the

time of water activation by magnetic field:

1 - cross-breaking strength;

2 - compression strength

These figures show that the samples which were made only by using magnetic

water have the durability less than 20-25%. So, preparing of the concrete mix by

using ABC-100 unit is more qualitative. But when we added more than 1 % of

nanoagents we observed reduction of durability degree during each of compression

tests and bending tests.

As result of our investigations we were conclude that nanoagents have a great

impact on the durability values of concrete mixes and processes of concrete structure

formation. It is reasonable to suppose that nanomodified concrete will have the best

values of durability and longevity.

Usage of the carbon nano-particles in the concrete production has great

prospective future.

By using ABC-100 you can also increase the fineness of cement grinding and

as result enlarge the grade of the cement.
