The water-cement ratio (w/c) of M20 grade concrete is typically 0.45.

• The w/c ratio is the ratio of the weight of water to the weight of cement in a concrete mix.

• For M20 grade concrete, the w/c ratio is generally recommended to be 0.45.

• This means that for every 1 kg of cement, 0.45 kg of water is used.

• The w/c ratio affects the strength, workability, and durability of the concrete mix.

KPIs for 4G and LTE Advanced

• KPIs for 4G and LTE Advanced include network availability, throughput, latency, and packet loss

• Network availability measures the percentage of time the network is available to users

• Throughput measures the amount of data that can be transmitted over the network in a given time period

• Latency measures the time it takes for data to travel from the source to the destination

• Packet loss measures the percentage of data packets that are lost during transmis...read more

The gauge of binding wire refers to its thickness or diameter.

• The gauge of binding wire is determined by its diameter.

• It is commonly measured using the American Wire Gauge (AWG) system.

• Thicker wires have lower gauge numbers, while thinner wires have higher gauge numbers.

• For example, a binding wire with a gauge of 16 is thicker than a wire with a gauge of 22.

Low throughput in 4G can be caused by various factors.

• Interference from other devices or networks

• Limited bandwidth

• Distance from cell tower

• Congestion in the network

• Hardware or software issues

• Inadequate backhaul capacity

• Poor signal strength

• Inefficient network architecture
