砂的细度模数检测数据

通过检测数据分析研判砂的细度模数，提高混凝土的强度，提高建筑物的安全性。算法：数据采集，对砂的细度模数进行检测。数据判定:若砂的细度模数在2.5%-3.0%，则砂的细度模数为符合，FM=(A2+A3+A4+A5+A6)-5A1/(100-A1) 公式中FM为细度模数，A1为5.0mm累计筛余百分率，A2为2.5mm累计筛余百分率，A3为1.25mm累计筛余百分率，A4为0.63mm累计筛余百分率，A5为0.315mm累计筛余百分率，A6为0.16mm累计筛余百分率。Analyze and determine the fineness modulus of sand via detection data, so as to improve the strength of concrete and the safety of buildings. Algorithm: Conduct data collection and detect the fineness modulus of sand. Data judgment: The fineness modulus of sand is considered compliant when it ranges from 2.5% to 3.0%. The correct calculation formula for fineness modulus is: $FM = frac{(A_2 + A_3 + A_4 + A_5 + A_6) - 5A_1}{100 - A_1}$. In this formula, FM represents the fineness modulus; $A_1$ is the cumulative sieve residue percentage of the 5.0mm sieve; $A_2$ is the cumulative sieve residue percentage of the 2.5mm sieve; $A_3$ is the cumulative sieve residue percentage of the 1.25mm sieve; $A_4$ is the cumulative sieve residue percentage of the 0.63mm sieve; $A_5$ is the cumulative sieve residue percentage of the 0.315mm sieve; and $A_6$ is the cumulative sieve residue percentage of the 0.16mm sieve.
