PROBLEM TO BE SOLVED: To provide a pavement structure which has an appearance excellent in harmony with the natural environment, has both water permeability and water retentivity, and has fungicidal properties, mildewproof properties, and water purification properties.
SOLUTION: A soil-based aggregate 10, a cement-based solidifying material 11, and bacteria 16 having fungicidal properties, mildewproof properties, and water purification properties are added into a mixer 12 to be sufficiently agitated and mixed. Subsequently a granulating agent 14 is added thereto, and the mixture is further agitated and kneaded to form a slurry mixture 15. The mixture 15 is installed on a roadbed, and cured and solidified to complete a pavement structure. As the pavement structure has a three-dimensional network structure, it exhibits excellent water permeability and water retentivity, and it contains the soil-based aggregate 10, thereby providing an appearance excellent in harmony with the natural environment. The pavement structure contains the microorganisms 16 having fungicidal properties, mildewproof properties, and water purification properties, thereby exhibiting excellent fungicidal properties, mildewproof properties and water purification properties over a long period of time after the construction.

PROBLEM TO BE SOLVED: To provide a method of preventing the caking of granulated blast furnace slag using anaerobic microorganisms to promptly and surely prevent the caking of the granulated blast furnace slag without using a chemical.
SOLUTION: The caking of the granulated blast furnace slag is prevented by that water content becomes 6-20 mass% , further adding an organic material into the granulated blast furnace slag so that organic material to be added becomes ≥100 g expressed in terms of carbon per 1 ton granulated blast furnace slag, keeping at 20-40°C under an anaerobic state to propagate the anaerobic microorganisms present in the granulated blast furnace slag and to neutralize the granulated blast furnace slag by organic acids produced from the anaerobic microorganisms.

PROBLEM TO BE SOLVED: To reduce a cost of ground improvement work by using a trimmed wood generated at a job site.
SOLUTION: Trimmed wood chips obtained by chipping thinnings generated at the job site are accumulated and fermented over a specific period, and are mixed at a prescribed rate with a ground hardener such as cement used for shallow layer mixing treatment of soft earth. These trimmed wood chips and the soft earth of an improving object are mixed and agitated to form an improved earth layer.

PURPOSE: To form functional ceramics by culturing a microorganism capable of forming an antioxidant substance, mixing the culture solution of the microorganism with clay, burning the mixture at a specific temperature.
CONSTITUTION: One or more microorganisms capable of forming an antioxidant substance such as an actinomyces, e.g. Streptomyces sp., a photosynthetic bacterium, e.g. Rhodopseudomonas sp., a lactic acid bacterium, e.g. Lactobacillus sp., a filamentous fungus such as Aspergillus sp. and yeast, e.g. Saccharomyces sp., are cultured in about 4% solution of molasses at pH3.10-4.5. Then, the culture solution is mixed with clay or a binder similar to clay, burnt at ≥500°C to give powdery or granular functional ceramics. The ceramics are usable for promoting growth of plant, cleaning dirty water and reducing an offensive smell.

PURPOSE: To improve corrosion resistance by putting mineralization microorganisms into a contact state in an atmosphere to enable mineralization and forming surface coatings in this place.
CONSTITUTION: The artificial surface of a limestony structural material, etc., to be treated is cleaned by a steam jet, etc. Next, the mineralization microorganisms selected from Bacillus brevis, Bacillus liqueniformis, Bacillus cereus, Bacillus megaterium, Pseudomonas stutzeri, Proteus mirabilis, etc., of Bacillaceae, Pseudomonodaceae and Enterobacteriaceae are applied on this surface by brushing, etc., and thereafter, the artifact surface is immersed into the nutritive medium of an aq. soln. contg. a carbon source, inorg. substances, etc., and is held for about 37°C. The surface is then rested for about 15 to 20 days. Consequently, the appearance changes as a whole. The microorganismic mineralization eventually links the particles of the stone material to each other and imparts a good tight adhesion property and high hardness to the surface.

PURPOSE: To temporarily and completely hold a shape and to thereafter return sand to the original condition by breaking down it so as to reuse it by mixing a proper amt. of a paste material and a decomposition enzyme with the sand.
CONSTITUTION: Thin film contg. a paste material is formed on the surface of each sand particle of a molding prepd. by adding a paste material to sand and adding proper amt. of water and a small amt. of a decomposition enzyme and tightening the mixture to hold a shape. As time passes, a natural self-adhesive polymer comprising the paste material is decomposed by the action of the decomposition enzyme and it is made into low mol.wt. and the viscosity is decreased and the shape is broken down to return the sand to its original condition. As the paste material, water-soluble paste material is pref. and e.g. either vegetable paste materials such as CMC (sodium glycollatecellulose), MC (methylcellulose) and treated starch or animal paste materials such as casein and gelatin can be used. In addition, as the amt. of the paste material, 0.5-3% to the sand is pref. in cases of CMC and MC and 10% to the sand is pref. in case of the treated starch. As the decomposition enzyme, such ones as cellulase, amylase (α-amylase) and protease which are suitable for each paste material are used.

The present invention relates to a method of manufacturing soil reinforced by microbe-based bio-binders and soil produced by the method. The bio-binders are not harmful to humans, do not cause environmental pollution and secure sufficiently the soil strength and resistance against wind. According to the method, the soil is prepared by binding sand whose major components are silica and alumina, ureolytic microbes, urea, calcium ion, and polymer fibers, and the content of polymer fibers in sand ranges from 0.05 wt % to 5 wt %. In addition, it is preferable that the microbes provide CaCO3 at a rate at 1˜7×10−9 g CaCO3 ppt cell−1 hr−1 under optimum conditions. |
