【発明の属する技術分野】本発明は、主として表面水の
状態が異なる複数の骨材及び水を計量するコンクリート
材料の計量方法及びプログラム並びに記録媒体に関す
る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method, a program, and a recording medium for measuring a plurality of aggregates having different surface water conditions and a concrete material for measuring water.

【０００２】[0002]

【従来の技術】コンクリートを現場配合する際、水量が
コンクリート強度等に大きな影響を及ぼすため、練混ぜ
時に十分管理する必要があるが、配合材料である骨材
は、その貯蔵状況や気候条件等によって含水状態が異な
り、湿潤状態の骨材を用いるとコンクリート中の水量が
骨材の表面水の量だけ増加し、乾燥状態の骨材を用いる
とコンクリート中の水量は有効吸水量だけ減少する。2. Description of the Related Art When mixing concrete on site, the amount of water has a great effect on concrete strength and the like. Therefore, it is necessary to sufficiently control the mixing during mixing. When the aggregate is wet, the amount of water in the concrete increases by the amount of surface water of the aggregate, and when the aggregate is dry, the amount of water in the concrete decreases by the effective water absorption.

【０００３】そのため、骨材の乾湿程度に応じて練混ぜ
時の水量を補正し示方配合通りのコンクリートを製造す
ることが、コンクリートの品質を維持する上できわめて
重要な事項となる。[0003] Therefore, it is extremely important to maintain the quality of concrete by correcting the amount of water at the time of mixing according to the degree of dryness and moisture of the aggregate and producing concrete as shown in the specification.

【０００４】ここで、湿潤状態における表面水の水量
（細骨材の表面に付着している水量）を表乾状態（表面
乾燥飽水状態）の細骨材の質量で除した比率を表面水率
と呼んでいるが、貯蔵されている骨材、特に細骨材は一
般に濡れていることが多いため、かかる表面水率を骨材
の乾湿程度の指標として予め測定し、その測定値に基づ
いて練混ぜ水量を調整するのが一般的である。Here, the ratio of the amount of surface water in the wet state (the amount of water adhering to the surface of the fine aggregate) divided by the mass of the fine aggregate in the surface dry state (surface dry saturated state) is defined as the surface water. Although it is called the water content, stored aggregates, especially fine aggregates, are generally often wet, so this surface water content is measured in advance as an indicator of the degree of dryness and moisture of the aggregates, and based on the measured value, It is common to adjust the amount of mixing water.

【０００５】そして、このような表面水率の測定は、従
来、細骨材が貯蔵されたストックビンと呼ばれる貯蔵容
器から少量の試料を採取してその質量及び絶乾状態での
質量を計測し、次いで、これらの計測値と予め測定され
た表乾状態の吸水率とを用いて算出していた。Conventionally, such a measurement of the surface water content is performed by taking a small amount of a sample from a storage container called a stock bin in which fine aggregate is stored, and measuring its mass and the mass in a completely dry state. Then, calculation was performed using these measured values and the previously measured water absorption in the surface dry state.

【０００６】[0006]

【発明が解決しようとする課題】しかしながら、このよ
うな測定方法では、わずかな試料から全体の表面水率を
推測しているにすぎないため、精度の面でどうしても限
界がある一方、絶乾状態の質量を計測するにはバーナー
等による加熱作業が必要となるため、実際に使用する量
に近い量を採取してこれを試料とすることは、経済性や
時間の面で非現実的であるという問題を生じていた。However, in such a measuring method, since the total surface water content is estimated only from a small number of samples, there is a limit in terms of accuracy. In order to measure the mass of a sample, it is necessary to perform a heating operation with a burner or the like, and it is impractical in terms of economy and time to sample a sample that is close to the amount actually used and use it as a sample. The problem had arisen.

【０００７】また、このような問題を補うべく、練混ぜ
状況をオペレータが目視で確認したり、ミキサの負荷電
流を参考にすることによって練混ぜ水量の調整を行うと
いった方法を採用することがあるが、かかる方法自体が
精度の低いものであり、結局、強度面で２０％近い大き
な安全率を見込まざるを得なくなり、不経済な配合とな
るという問題も生じていた。In order to compensate for such a problem, a method of visually confirming the mixing state by an operator or adjusting the mixing water amount by referring to the load current of the mixer may be adopted. However, such a method itself has low accuracy, and as a result, a large safety factor of about 20% has to be expected in terms of strength, and there has been a problem of uneconomical blending.

【０００８】特に、密度、粒度などの種類が異なる複数
の骨材を混ぜ合わせる場合には、上述した問題はさらに
深刻となる。In particular, when a plurality of aggregates having different types such as density and particle size are mixed, the above-mentioned problem becomes more serious.
