摘要： PROBLEM TO BE SOLVED: To provide equipment for managing filling of concrete, which enables the visual checking of concrete filling conditions by enabling a speed of press-fit of concrete into a steel pipe to be adjusted while being visually checked.SOLUTION: The height of an upper surface 14a of concrete, which ascends in an internal space 12a by making the concrete 14 press-fitted and infilled into the internal space 12a of the steel pipe 12, is measured by a level measuring instrument 16; and the upper surface 14a of the concrete, which ascends in the internal space 12a, is imaged by an imaging camera 18. A measured value measured by the level measuring instrument 16 is displayed as a line graph, which is two-dimensionally changed along a time base along with the ascent of the upper surface 14a of the concrete, on a management monitor 22; placement conditions of the upper surface 14a of the concrete, which are imaged by the imaging camera 18, are displayed on the management monitor 22; a steel pipe image similar to the steel pipe 12 is generated and displayed on the management monitor 22; and the measured value is displayed as a bar graph, which is one-dimensionally changed along with the ascent of the upper surface 14a of the concrete, in the state of being superposed in a steel pipe image-displayed location.

摘要： PROBLEM TO BE SOLVED: To enhance the production efficiency of lightweight concrete using aggregate low in water content.
SOLUTION: When lightweight concrete is manufactured through a dry mixing process S40 and a kneading process S50 by using artificial lightweight aggregate with a water content of 5% or below, correction water and kneading/mixing water are collectively charged in the kneading process S50 to reduce supply labor of water. In the dry mixing process S40, correction water is not charged at all. Further, the amount of correction water is prescribed as an amount estimated to be absorbed within the manufacturing time from the start of the kneading process S50 to the completion of the finishing process S70.

摘要： PROBLEM TO BE SOLVED: To complete joining work quickly using a hardening filler having good characteristics in a joining method between a PCa column member and a PCa column/beam joint part block in which the hardening filler is injected into a joint space formed between an upper face of a column head of the PCa column member and a lower face of the PCa column/beam joint part block, and into a plurality of insertion holes for column main reinforcements of the PCa column/beam joint part block by injecting the hardening filler into the joint space.
SOLUTION: Cement mortar having fluidity is fed into the joint space 26 to allow it to flow from a lower end of each of the insertion holes 16 for the column main reinforcements so that it may fill the inside of the holes. Before the highest top end of the top ends of the hardening filler rising in the insertion holes reaches an upper end of the corresponding insertion hole, injection of the hardening filler is stopped to leave an unfilled part near the upper end of the insertion hole as a margin. The unfilled part is filled with the hardening filler injected from an upper end of each of the insertion hole.

摘要： PROBLEM TO BE SOLVED: To provide a method for measuring an air volume in a concrete, which measures the concrete in which artificial lighter weight coarse aggregates are employed, accurately and simply so as to be carried out readily as an on-site check test.
SOLUTION: In the method, a mortar air volume is calculated from an apparent air volume obtained from a measurement of a concrete sample to be measured, by using following equation: y=0.3x-0.8, where x is the apparent air volume (%); and y is the mortar air volume (%). An applicable range of the equation is set so that the apparent air volume x ranges from 10% to 20%. A conversion table of the relation between the apparent air volume and the mortar air volume, in which values of the apparent air volume correspond to respective values of the mortar air volume in 1% steps, is prepared beforehand, thereby enabling the mortar air volume to be obtained, without calculating it at each time on the site.

摘要： PROBLEM TO BE SOLVED: To estimate a substantial unit water content. SOLUTION: First, at a water absorption content measuring step, aging change of water absorption content of artificial light-weight aggregate is measured. At a volume measuring step, concrete containing the aggregate is placed, and then aging change of volume of the placed concrete is measured. Thereafter, at a water absorption content acquiring step, the concrete is placed based on the measured result of the volume measuring step. Then, a time until the volume of the concrete is not changed is obtained, and the water absorption content of the aggregate at time point of elapse of the time is obtained based on the measured result of the absorption content measuring step. And, at a unit water content calculating step, an amount of water contained in the aggregate is calculated based on the water absorption content obtained at the absorption content acquiring step. And, the calculated water content is subtracted from apparent unit water content, thereby calculating substantial unit water rate.

摘要： PURPOSE: To nondestructively measure water content by obtaining the relation ship between the water content and the thermal conductivity of a reference sample concrete which has the same material and blend as those of body con crete according to predictable temperature conditions in advance and obtaining the thermal conductivity of the body concrete using the twin comparison method. CONSTITUTION: Measurement sample side probes 7 and 8 measure the temperature of a body concrete 13 and reference sample side probes 9 and 10 measure that of a reference sample 14. The probes 7 and 9 are provided with a heater and a thermocouple and the probes 7 and 8 are provided with only a thermocouple, thus individually measuring the sample temperature at a part which is not affected by a thermal source and heating in a sample and hence obtaining the temperature difference between the both. A body 5 receives the temperature information of the probe, transmits an interface 6 for sending the information to the body 5 and a command for supplying heat, and further receives such information as a voltage related to the temperature change of the probe, thus obtaining thermal conductivity. A corresponding water content is obtained from the relationship curve between thermal conductivity and water content.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing light-weight concrete to be used with adequate softness without necessity of waiting until it becomes adequately soft and without necessity of discarding. SOLUTION: Water reducing agent having satisfactory dispersing performance is added at the time of kneading initial overall concrete material by using overall or partly dried light-weight aggregate. And, after kneading the concrete thereafter, at least one type of admixture selected from water reducing agent having different component from that of the previous agent and fluidizing agent is post-added, and again kneaded.

摘要： PROBLEM TO BE SOLVED: To provide a method for suppressing carbonation of lightweight concrete having satisfactory working property with a light weight and excellent in appearance and strength by mixing a lightweight aggregate dried with a percentage of water absorption of a prescribed value or less, cement, a water reducing agent and water. SOLUTION: A lightweight aggregate dried in absolute dry condition or with a percentage of water absorption of 50% or less, cement, a water reducing agent and water are mixed together to suppress carbonation. As the cement, alumina cement, general Portland cement, fly ash cement or the like is used, and as the water reducing agent, polycarboxylic acid is used. As the lightweight aggregate, natural lightweight aggregate is used, and an artificial lightweight aggregate may be used together. The specific gravity of the lightweight aggregate is set to less than 1, and the ratio of water to cement is preferably set to 50% or less, particularly, 20-50%. Other admixtures may be blended. The materials are put in a mixer followed by kneading. proportioning water and the water reducing agent are put thereto to perform a main kneading, and the resulting mixture is placed in a form. Thus, carbonation is suppressed to improve the durability, and the working property can be enhanced with a light weight.
