Abstract

The present invention provides a concrete masonry unit composition for automated block machines, comprising cement, aggregate, sand and microbeads with respect to total weight of the composition. After a predetermined number of days, the composition forms a plurality of concrete masonry units that meet the requirements under standards ASTM C90 as measured according to ASTM C140. Each of the concrete masonry units comprises a solid portion and at least one hollow portion boring through the solid portion. The solid portion comprises 0.25 to 0.5 percent of microbeads with respect to total weight of the composition.

Claims (32)

1. A concrete masonry unit composition for automated block machines, the composition comprising:

13 to 23 percent of cement with respect to total weight of the composition;

20 to 30 percent of coarse aggregate with respect to total weight of the composition;

60 to 66.75 percent of fine aggregate with respect to total weight of the composition; and

0.25 to 0.5 percent of microbeads with respect to total weight of the composition.

2. The composition of claim 1 , wherein each of the microbeads has a diameter of 0.1 millimeters to 3.2 millimeters.

3. The composition of claim 2 , wherein each of the microbeads has a diameter of 0.2 millimeters.

4. The composition of claim 1 , wherein the cement comprises Portland cement Type I, Type IA, Type II, Type IIA, Type III, Type IIIA, Type IV, Type V, modified cement, hydraulic cement, blast furnace slag cement or a combination thereof.

5. The composition of claim 1 , wherein the fine aggregate comprises sand.

6. The composition of claim 1 , further comprising one or more of water reducer agents, bonding agents, color agents and water proofing agents.

7. The composition of claim 1 , wherein the coarse aggregate is normal weight aggregate or lightweight aggregate.

8. The composition of claim 1 , wherein the fine aggregate is normal weight aggregate or lightweight aggregate.

9. A concrete masonry unit composition for automated block machines, the composition comprising:

13 to 23 percent of cement with respect to total weight of the composition;

20 to 30 percent of coarse aggregate with respect to total weight of the composition;

60 to 66.75 percent of sand with respect to total weight of the composition; and

0.25 to 0.5 of microbeads with respect to total weight of the composition.

10. The composition of claim 9 , wherein each of the microbeads has a diameter of 0.1 millimeters to 3.2 millimeters.

11. The composition of claim 9 , wherein the cement comprises Portland cement Type I, Type IA, Type II, Type IIA, Type III, Type IIIA, Type IV, Type V, modified cement, hydraulic cement, blast furnace slag cement or a combination thereof.

12. The composition of claim 9 , further comprising one or more of water reducer agents, bonding agents, color agents and water proofing agents.

13. The composition of claim 9 , wherein the coarse aggregate comprises normal weight aggregate or lightweight aggregate.

14. A concrete masonry unit composition for automated block machines, the composition comprising:

13 to 23 percent of cement with respect to total weight of the composition;

20 to 30 percent of coarse aggregate with respect to total weight of the composition;

60 to 66.75 percent of fine aggregate with respect to total weight of the composition;

0.25 to 0.5 percent of microbeads with respect to total weight of the composition; and

wherein each of the microbeads has a diameter of 0.1 millimeters to 3.2 millimeters.

15. The composition of claim 14 , wherein each of the microbeads has a diameter of 0.2 millimeters.

16. The composition of claim 14 , wherein the cement comprises Portland cement Type I, Type IA, Type II, Type IIA, Type III, Type IIIA, Type IV, Type V, modified cement, hydraulic cement, blast furnace slag cement or a combination thereof.

17. The composition of claim 14 , wherein the fine aggregate comprises sand.

18. The composition of claim 14 , wherein the coarse aggregate comprises normal weight aggregate or lightweight aggregate.

19. The composition of claim 14 , wherein the fine aggregate comprises normal weight aggregate or lightweight aggregate.
